Accurate Firearm Design
When I began to write my book the “Range Officers Handbook”, I envisaged it would be a short book concerning the Range Officers duties and of course coaching in all of the disciplines of shooting, of course it grew with the realisation that to explain internal, external and terminal ballistics, when you have to have the expectation that the reader know’s nothing about the subject. Even more difficult was to describe to the reader how to train the mind to shoot, thank goodness we don’t have to repeat this in this instance but again I originally, started out to produce a book on small arms ballistics that would be understandable be of practical use to the average shooter. Again the same principles applied, I could hardly expect the reader to understand ballistics unless they had some prior knowledge of the material with which to work, so chose ‘design ‘ as an angle of explaining it. So if anyone who desires to gain a knowledge of ballistics as applied to semi-automatic weapons they must have some knowledge of their design, manner of operation, and limitations. Unfortunately, with current legislation in Australia the subject material is only found in Museums, most not even on public display. So I have to provide more information before the reader can ascertain the subject we are discussing.
The first outstandingly successful semi-automatic rifle action produced were the simple blow-back as seen in the Winchester Models of 1903, 1905, 1907, most designed by John Moses Browning. This type is decidedly limited in the breech pressure it will handle, and fairly straight cartridge cases are required. With a tubular magazine in the butt-stock it has been very successful with the .22 caliber rim fire cartridges, and for such ammunition this type will probably remain in demand for many years in countries free enough to allow their citizens to own them. This system has become practically obsolete for centrefire cartridges because the limiting factors of permissible breech pressure and case design have prevented until recently the use of modern high velocity cartridges.
The second outstanding semi-automatic action developed was the recoil operated, action as seen in the Browning and Remington automatic shotguns. It was the most popular for many years and after the patent expired in the 1940s, it was made by hundreds of other manufacturers all over the world from Australia to the Philippines, France and South America, perhaps because they have been unable to find another design which was quite so good. This action is so reliable for shotgun shells that it will probably remain in demand and be manufactures in free countries for many years to come. In the last 30 year designers such as Benelli have been able to produce a self loading shotgun action that is not so bulky and heavy as the Browning but still as reliable. We are really still at the beginning of design potential with shotguns as the difficulty has been the rimmed case, the variable plastic dimensions and the weight of the lead shot.
While the design of a reliable and successful semi-automatic action for rim fire cartridges and shotgun shells was solved rather early in America, this was not true of a similar action to use high velocity, high pressure rifle cartridges. Here the problem proved much more difficult. When those cartridges are fired, the cases grip the chamber walls much tighter than do low pressure loads, and this tight gripping increases very materially as the barrel and chamber become heated from rapid firing. A very powerful primary extraction is required. The fired case has to be “torn” loose from the chamber with a powerful back motion of the bolt, combined with an effective and sure extractor claw. This violent rear motion of the breech bolt continues after primary extraction has been accomplished, and at the rear end of the bolt throw it must be cushioned or stopped by some form of buffer. The operation is thus quite violent. A semi-automatic action for high power cartridges is usually designed with the thought of possible military use, and other details become important such as operation in all positions and temperatures, and in the presence of dust, dirt, sand, and mud. Also the various parts should be interchangeable, be diss assembled by hand, and readily replaceable.
With the introduction of semi-automatic arms the Armies of the world had to concede one thing to the inventor. They concede that the soldier will be fairly well instructed in the use, care, and maintenance of his weapon, and adequately supplied with proper cleaning and lubricating materials. In other words it is conceded that the user of such a weapon is operating a gas engine. He must understand it and care for it. If he does this fairly well the mechanism will prove reliable and dependable.
Between the World Wars of the 20th Century the major powers researched and reviewed hundreds of designs for a new semi automatic battle rifle, the first one that was adopted was the M1 Garand in 30-06, the main reason for its choice was that the Army had millions of stock blank left over from World War One so the one they chose could utilise them in a slightly different configuration. Although the inventor, Mr. John C. Garand, was’ assisted by the extremely skilled personnel at Springfield Armoury, where he was an ordnance engineer, it took him from 1918 to 1930 to develop and perfect his rifle, which is indicative of the difficulty of the problem. It was finally adapted as the standard Infantry rifle in 1939, and manufacture was started at Springfield Armoury and by the Winchester Repeating Arms Company. It remained the U. S. Army standard issue rifle until 1958 on the introduction of a major modification the M14 in .308 nato.
The Garand is gas operated, the gas port being about an inch in rear of the muzzle, so that practically speaking the bullet has departed from the muzzle, during which time the breech is solidly locked, before the gas piston starts to operate. The bolt is symmetrically locked by two lugs at its front end, in basically the same manner as seen in the Mauser 1898 mechanism. The double column box magazine within the receiver is charged with a clip of eight rounds of .30-06 cartridges, the entire clip being inserted in one motion. Upon firing the eighth round the empty clip is ejected automatically, and the breech remains open for the insertion of a new clip. The mechanism is such as to provide a very excellent trigger pull, and the rifle is completely dis-mountable by hand and with the aid of a cartridge. An expert shot can fire from twenty-four to thirty-two well aimed and squeezed shots per minute.

Swiss Army Tool Kit $135. plus post
RE: Victorinox Multitool, There is a Strong rumour that these and thousands of other folding Knives are about to be added to the Customs Prhibitied Imports list. Why?? But if you want one for sure phone now.
Thought I might give a quick review of the above multi tool as I have had one for five years now. First thing I observed was that the locking mechanism leaves ALL the others for dead and is easily manipulated. The range of tools is well thought out and I have found uses for everything from the two knife blades (straight and serrated) as well as the screwdriver and the pliers which I have used to cut 3mm high tensile wire after watching another brand which cost twice the price of mine snap through the head of the pliers. Even down to the saw which whilst small is extremely efficient with its twin rows of teeth. My tool lives on my belt and some function on it is used daily, from one of the blades to screwdrivers to bottle and can openers. When I am in the bush my tool is there and I reckon that it is more of a survival knife than any of the so called “survival” knives and I should know, as the bush to me is the edge of the Great Sandy Desert! I have lived here now for three years and the same tool has been on my belt all that time and still looks pretty much brand new despite its daily use! Yes the leather pouch is a little weather worn but after three years out here –so am I! I have observed SOG’s and Leatherman tools break and snap and fail to do many jobs out here but give the Swiss tool a go and it has NEVER LET ME down – Not once! In one of the harshest climates in the world this tool has been tested and not found wanting like many others. In my opinion if you want the best buy a Victorinox Multitool – Three years here is like a life time of normal use.

Editors Note. Andrew Norris lives in Newman, at the edge of the Little Sandy Desert. He manages the Ranger and Emergency Services for the local shire Council. IT is the largest shire in the world, as it goes from the WA coast and the start of the eighty mile beach to the NT border covering over 370,000square kilometres. He regularly ventures into the Great Sandy desert to deal with Aboriginal communities there on a number of levels. He has tested his knife from Telfer, Cotton Creek, Kiwikurra, Punmu, Kunawaritji, Jigalong, and all points in between and states that it has never let him down.
Thoughts For the Week.
The Draft Weapons Act for Queensland, proposing to introduce another round of impositions, eventually on all Australian citizens, as if they succeed in one State they will quickly adopt them in the other Australian States on the old lie of Uniform Gun Laws. They have never been uniform only un informed.
Before we allow our lives and property to be removed, and put our necks on the block of “In Government we Trust”, we should realise that these new laws written by the Police enforcers, give the Police far more power over the home owner, (remember your Home is your Castle) and far more decisions making power over your rights and property.
When your M,Ps, your representatives, ‘give you up’,(the law abiding citizen) and put you in the hands of known Criminal associations ( Australia’s Police Forces) how can you rate the care factor of those whom they vote for. Minus, or smaller than a Knats nose.
To clarify my assertion that the Police are known Criminal associations, I must first say that I have personal friends, that were good policemen of 35 years standing who I believe are uncorruptable and had morals of the highest standards, so on that basis my assertion does not personally include every policeman. On the other hand I have well know policemen on the other extreme who would make Adolf Hitler or Joseph Stalin look like gentleman. I have made complaints about Police to the CJC and the CMC, I and my family have been offered Witness protection by the CJC, but as I do not trust the integrity of the protectors, declined the invitation. In response to my whistle blowing, I received 2000 or so charges 350 indictable, after eight years of court appearances two jury trials, all were either dismissed, or I was found ‘Not Guilty’. Being the subject of countless threats, futile searches and the frustration that there is no one out there that can help, no umbrella of justice and truth where you can seek protection, I am qualified to make these observations of 150 years of Police Corruption in Australia.
Police Power Will be Used Against the Good to Protect the Evil.
It is proportionate, the more they get, the more they will abuse the innocent. Police corruption is an international problem but Australia could be the worst example as we now have full time investigative commissions such as the CMC and ACC and it still has not improved.
Original policing of Australia inevitably began as early as the First Fleet itself. Many in both the Magistracy and police were notoriously dishonest and ineffective. A significant factor in policing of that time was the relationship between police and criminals with the active involvement of police in the very crimes they were supposed to suppress. In August 1838 the son of the founder of Melbourne Henry Batman, then Chief Constable of the Melbourne City Police, was dismissed for bribery. The history of Australian policing is just a list of hundreds of Royal Commissions, Inquiries, and Commissions to investigate the corruptions even within the Investigating Commissions. Thousands of official reports and hundreds of thousands of complaints of Police Corruption.
The Select Committee on Police in 1852 was told that ‘there has been, in the case of several detective officers, a most suspicious suddenness in getting rich’. Frequenting brothels and drunkenness were endemic amongst police. So much so, that in 1854 a prison was built in Richmond Victoria to hold police who broke the law. The Royal Commission into the Ned Kelly hunt (the Longmore Commission) found widespread corruption it shattered a number of police careers in addition to that of Chief Commissioner Standish. Winch and Larner, were involved in prostitution, gambling and borrowing from hotelkeepers, whilst being protected by Standish. It found “inimical to the public interest’, a ‘nursery of crime’ and a department whose ‘system of working (was) so iniquitous that it may be regarded as little less than a standing menace to the community’.
The most infamous was Chief Commissioner Sir Thomas Blamey of the Victorian Police exposed in a Royal Commission into the Brophey shooting which found that the Chief Commissioner’s was involved with prostitutes in the car where Brophey was shot. Jury rigging, with the police involved on both sides they found that the Criminal Squizzy Taylor was a paid police informer/organiser of the Jury rigging. The Beach Report found “..the existence of a ‘brotherhood syndrome’ whereby police at all levels would do whatever was required to protect workmates He also found that police would conspire and commit perjury as necessary, either in court hearings or when appearing before him.”
Corruptions is especially epidemic where police have been expected to enforce laws which many citizens have regarded as petty infringements of their liberties.
There has also always been a close connection between illegal gambling, drink/drug prostitution and police corruption. This kind of pattern arises because although governments can readily make something unlawful, they can’t make it unpopular.
History has demonstrated that corrupt police are adept at using ‘the system’ to their advantage. They are able to build alliances within and outside the Force to exert political and other pressure to circumvent accountability and evade justice. Since the 1960s, Royal Commissions and Boards of Inquiry in Australia have reported on entrenched and systemic corruption with local police forces. Despite jurisdictional differences, there are obvious similarities both in the nature of the corrupt behaviour. In particular, the Commissions of the Moffitt, New South Wales (1973–1974), Woodward, New South Wales (1977–1979), Williams, Canberra (1977–1979) and Costigan, Canberra (1980–1984) Royal Commissions and the Connor Board of Inquiry into Casinos, Victoria (1982–1983) were searchlights revealing what hitherto had been a formidable but shadowy force in Australia. Each inquiry identified various levels of corruption affecting police and other public officials.
The work of Lusher, New South Wales (1979–1981), Wood, New South Wales (1997), Fitzgerald, Queensland (1989), and Kennedy, Western Australia (2002) concentrated on problems of long-standing corruption in the police forces in their respective states. Beach Inquiry (1975), the riskof corruption is ever-present, as the Ombudsman’s Reports on the Ceja Task Force (Drug Related Corruption, 2003 and 2004).
In a recent newspaper articles concerning the Victorian Police quote, Ombudsman George Brouwer warned confiscated drugs were not being stored securely at the Victorian Police Forensic Services Centre, paving the way for corruption. The Ombudsman’s report, tabled in Parliament, outlined “significant issues regarding the security and storage of drug” exhibits at the MacLeod centre which stores some 18,000 drug items. In the report, Mr Brouwer admitted he did “not have confidence that all drug exhibits have been accounted for until a full external audit has been undertaken” and warned electronic records of drug exhibits were inaccurate. Forensic drug and alcohol branch head Cate Quinn was yesterday suspended. In March, the Ombudsman found police abused recording procedures to improve crime clearance rates.Last month, Victoria Police was under the microscope with a scathing Ombudsman report about a series of costly blunders and dodgy contracts that left the force’s IT budget $39 million in the red.
Chief Police Commissioner Caught with Magazine and Ammunition At the Airport.
Documents obtained by ‘The Australian’ using Freedom of Information legislation show that within hours of Mr Overland being stopped with the nine semi-automatic handgun bullets in his hand luggage before boarding his return flight to Melbourne, the AFP and Victoria Police had agreed a strategy to issue a statement omitting anything that could identify him – unless the incident leaked. The OPI said today that after the magazine clip containing the bullets was found in Mr Overland’s carry-on luggage during a routine boarding scan in Canberra, AFP officers attended the scene,
Separate Laws For the Police.
“Mr Overland emphasised that he did not seek preferential treatment and wished to be treated in the same way as other citizens.”
At the time the incident was made public in March, Victoria’s police union head Greg Davies said: “If it was a constable or member of the public, you would be hung, drawn and quartered . . . you and I would still be in handcuffs and remanded in custody. I am not sure which end of the scale it should be but you can’t carry a set of nail clippers on to a plane.”
Victorian Police also have trouble with records not guns?? The first statewide audit of firearms in 20 years has found nearly 200 weapons can’t be located, which senior police insist is down to accounting errors and not actual cases of missing guns.”186 unaccounted weapons, including three revolvers, one long-arm and others used for training and ballistics testing,””I think it’s poor record-keeping. Let’s be honest about that,” Deputy Commissioner Kieran Walshe told reporters on Tuesday. With their record how could we believe they are honest. With their record how can they put them in charge of the ‘Candy Jar’, the Firearm Registry?
Guns in Roof St Kilda Police Station
“..investigators found marijuana seeds hidden under the bottom of a drawer. Looking around more closely, they saw dislodged ceiling tiles covered with ‘dirty paw marks’. A search of the ceiling located a sawn-off shotgun, a revolver, two imitation pistols and illegal knives….$200 cash, car number plates, a metal baton, drugs (including amphetamines) and credit cards. Several bottles of whisky, beer and wine were also found. Numerous contemporary media outlets reported the search.
Concealment of the items seemed to have been comparatively recent. The most obvious inference was that they were illegally obtained and
may have been intended to plant on suspects. This was not the first time that illicit items had been hidden in a false ceiling at the St Kilda Police Station. In 1988, a cache of nine handguns was found in the ceiling space of the then Armed Robbery Squad and the former Major Crime Squad offices at the St Kilda Road police complex. Despite a nineteen month
investigation, none of the items located could be linked to any member at the station.”
Can you imagine Police finding those in your ceiling ‘twice’ and not charging anyone.
They information for this article came from “Victoria Police and the problem of corruption and serious misconduct”, and was put before the Victorian parliament in February 2007. This is not just a Victorian problem the same if not worse has occurred in NSW with the 1200 missing Glocks from there Police Force and in an article in the Canberra Times by Fia Cummings in 2001 the Defence Forces admitted losing 5000 firearms 1800 from Moorebank NSW. In Queensland, the Police liberated thousands of firearms and millions of dollars for their own use during the Buy Back. Sometimes the same Police handgun has been lost, recovered from Criminals and then after it being established as Court evidence has been found again in the hands of Criminals. Maybe the Queensland Police just hire them out to their mates.
Yet, the politicians ignore any real investigation into the Police and put our information on ‘Crimtrac’ and make the Police our jailors. They write the laws to chain us down and then exploit us, they taunt us and use us as fair sport for their entertainment at our expense. While they can carry on with their criminal enterprise as they please. Of course, they want the general public useless and defenceless. If you feel you would like to oppose this latest form of slavery, contact your local politician before you allow them to fix heavier chains to your arms.

It’s a week since I received a copy of “Range Officers Hand Book” and since that time I am nearly at the half way mark. I’m amazed at the at the number of subjects you have covered making it one of the most informative books to be added to my collection. It must have taken you a considerable amount of time and experience to publish the book with information not available in other popular Gunsmith manuals. I would recommend the book to “Range Officers” and anyone interested in the sport of target shooting and hunting.

Understanding Reloading Ammunition
Continued from previous editions on Powder Manufacture.
Powder Coatings.
The moist powder is bagged (normally 50 lbs. each) and transported to the coating building. Here Dinitrotolulene (DNT) will be applied in the form of a thin external coating to control burning rate. This relates to its suitability for different cartridges and it is given a separate designation on the containers. This is why you must never mix powders or load cartridges with powder that you do not know it burning rate or the identifying designation on the container does not match the loading information you are using.
This coating which controls the burning rate is applied while the powder is still moist from water drying. Even so, coating is still a dangerous process.
The coating building is barricaded. Large copper barrels shaped like a flattened ball are used to apply the coating by tumbling powder, DNT and water together. The barrel is charged with (for one example) half a ton of powder, 96 lbs. water and 65 lbs. DNT. The drum is sealed and operators move out of the barricaded area. The drum rotates at about 20 rpm for approximately one hour.
At the end of the tumbling, the DNT will have uniformly coated each kernel. Only the outside of the kernel is coated. Though the DNT may have built up over the perforations of some kernels, sealing them, it burns off quickly and does not affect the general burning characteristics of the powder. The powder is then transferred to a wash house where it is hosed down with water and screened to remove lumps and kernels stuck together. It is then air dried. Warm air is circulated through it in tanks. Several hours may be required for this process.
Once dry, the powder requires only “glazing” or coating with graphite. This coating has no effect upon the powder’s performance. It could be used without it. However, the graphite prevents build up of static electricity which could fire the powder. It also makes the powder flow freely in packing and loading machines. The distinctive gray/black colour of canister powders does not appear until the graphite is applied. Prior to that point the kernels are relatively light in colour.
The powder is placed in a drum similar to those used for coating and tumbled with a very small amount of graphite. As an example, 1,1/2 lbs. of graphite will treat 5,000 lbs. of powder. After about an hour of tumbling, the charge is dumped and placed in 50 lb. bags for movement to the blending machine. There, bags from different batches of powder are emptied into a barrel to make up a “pre-blend” charge. Rotation of the drum thoroughly blends the powder together and it is again bagged. A second blending takes place in the same way, only this time, bags from different pre-blend batches are mixed.
Upon completion of the final blending, the powder is packaged with the assurance that ballistic qualities will vary very little from lot to lot. At this point, perhaps you’ll wonder just what constitutes a “lot” of powder. Lots generally consist of a quantity that can be easily and conveniently handled. During the wars, lots consisted of 50-55,000 lbs. simply because that was the capacity of the railroad cars available for shipment. Thus each carload was a separate lot and there were no portions of lots left over after loading. In peace time, powders for the handloading trade are produced in smaller lots. For example, if the estimated market requirements for a given period is 10,000 (or 20,000) lbs. of a particular powder, then a production order for that amount of powder will be issued. The powder will be then produced, packaged as a single lot and placed in the magazine for filling future orders. If, on the other hand, cartridge loading factories are producing .223 rem 5.6 x45 or 7.62mm cartridges at a high rate, requiring continuous deliveries of powder, it will be shipped in the traditional individual carload lots.
It goes without saying that continuous testing takes place throughout the production processes. Once the powder is completed and blended and a lot number assigned, samples are fired extensively for pressure and velocity to insure that it meets the proper specifications. Powders for the reloader must be very uniform from lot to lot. Powders for commercial or military purposes can vary without causing trouble, since the users can adjust loading data to produce standard velocities and pressures. For example, each lot received at a loading plant is tested and charge weights are calculated and proven by actual firing before that lot is used.
