HOW THE ELECTRONIC EAR MUFFS WORK
These electronic ear muffs are a high standard ear muff in design, they are made to feel light and comfortable for all day use. They can be used as standard ear muff when the electronic component is not turned on and will passively reduce noise like any normal ear muff. They have a standard noise reduction rating of 29 decibel and are a Class 5.
Once turned on the microphone, located at the top of the ear muff, will pick up and amplify ambient noise. If some one standing next to you talks, their voice will be amplified through the speakers in both ear muffs. Should there be a loud noise, such as a firearm, the electronic ear muffs will automatically cut out and block the loud noise. The electronic ear muffs are designed to attenuate noise about 85 decibels, meaning that they will block out instantly, once the noise reaches a certain level. The electronic ear muffs allow you to control the volume level of ambient noise around you. On the shooting range with constant loud reports, the electronic ear muffs will block this noise. For range instructions or to communicate with another person, you can instantly hear them speak.
At the range or anywhere ear protection is constantly required, but you also need to hear instructions from others or you wish to be more aware of the ambient sound around you, these electronic ear muffs are what you need.

As already purchased by members of all Shooting Organisations.Some have even bought two copies one for home and one to take to the club. See Book Reviews by Nick Harvey in Sporting Shooters and Guns Australia in our new Gun Book Category.
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.

The Norinco JW 105. in .223 Remington.
The Norinco JW 105. in .223 Remington.
This is the (Jain Way) JW Model 105, Sometimes called Norinco. These rifles are made in the same factory that manufactures the now famous JW 15 .22 rifle (the Brno Mod One Copy) if you have had a JW15 or know of anyone who had one, you will know that they shoot sometimes better than the rifle they imitiated. These JW105 s are in .223 Remington calibre and have a five shot detachable magazine. They also come with Weaver style mount bases and Quick Detachable studs for QD sling swivels If you look carefully at the close up photograph you will notice a shiny silver colour, at the breech face,the camera has picked up the chrome plating from inside the chamber. The Chinese are the only non-military manufactures that can afford the chrome process of plating the Barrels and Chambers. They have also chromed the forward section of the Bolt. Chrome plating gives the best protection against erosion and corrosion than anything else besides regualr cleaning. The JW 105 is a copy of the Gevaram and Krico that was very popular in the 1950s and 1960s, they were very good quality but I believe that Gevarm had to stop making them as the were too expensive to produce.
These are the best value .223 remington centre-fire, repeating rifle on the market.

Accurate Firearm Design
The Blowback Breech Action.
The most basic form of automatic mechanism is known as the “blowback.” It is also often correctly called the ‘direct recoil action’ . Most if not all, are not pure “blowback’ or ‘recoil’ actions as they are all delayed ‘blowback’ actions to some degree. The common feature is that it has a sliding breech block without any locking means, but of a rather heavy weight, and held against the head of the cartridge by a strong spring known these days known as Recoil Spring, but is properly described as a Counter Recoil Spring.
Deliberate for a moment the pressure in the barrel when the cartridge is fired. At the start, when the bullet has just left the case, or when it is about an inch or two up the bore, the pressure is at its peak or highest point. As the bullet passes up the barrel the space in the bore in which the gas can expand increases progressively, and the pressure likewise decreases, so that when the bullet is just about to leave the muzzle the pressure throughout the bore and in the now empty case, and pressing against the interior of the head of the case, is roughly only about one-fourth of the peak or maximum pressure. When the bullet leaves the muzzle the pressure drops rapidly to zero, but for a very brief interval some pressure remains in the chamber, and is enough to surely push the bolt back and eject the fired case. The firearm designer calls this the ‘residual pressure’.
When a simple blowback weapon is fired the bullet moves first because it weighs so much less than the breech block. The sliding breech block also moves to the rear, but it starts and moves much more slowly because the inertia due to its weight and the pressure of the counter recoil spring has to be overcome. Thus by the time the bullet has reached the muzzle the breech block and the case in the chamber have moved to the rear only a short distance, in some guns perhaps 1/8th to 1/4 of an inch. During this small movement the high pressure within the case is pressing the mouth of the case, and the thinner portion of its forward walls against the walls of the chamber, and preventing the gas, while at high pressure, from coming past the case and out of the breech into the mechanism. Then the bullet leaves the muzzle, and the rearward momentum which the sliding breech block has acquired, plus the impetus of the residual pressure, continues to force the block to the rear, compressing the counter recoil spring, until the block comes to rest at the stop or buffer at the back end of the receiver. As the block thus moves to the rear it extracts and ejects the fired case. When the bolt is all the way to the rear it has uncovered the top cartridge in the magazine, and this cartridge then rises slightly from the pressure of the magazine spring until it is stopped by the lips of the magazine. Also while the block is moving to the rear it cocks the hammer if the weapon in question is hammer-fired. Now the strongly compressed counter recoil spring moves the block forward again, and as it moves forward its forward lower edge comes up against the head of the top cartridge in the magazine, held in just the right position by the magazine lips, and forces this cartridge forward, out of the magazine into the chamber. The action is now closed, the cartridge is in the chamber, and the hammer is cocked, and everything is ready to fire again as soon as the trigger is pressed. This type of mechanism is “timed” so that all these movements occur at the proper pressure times, and so that the block will move only slightly to the rear while the pressure remains high and the bullet remains in the bore, by regulating the weight of the breech block and the strength of the counter recoil spring although the last is relatively unimportant.
There are several limiting and important details with a simple blowback action such as this. The breech pressure of the cartridge should not be too high; in fact it should be relatively low for this type of mechanism is correct. For many years the example that the .30-06 cartridge, which has a very high breech pressure, but to provide sufficient inertia and timing for its pressure it was calculated that the breech block of the simple blowback would have to weigh about 27 pounds. In the last ten years that theory has been shattered as lightweight bolts have been tried without any locking lugs and the large bottle neck cases stay firmly sealed or fixed in the chamber, extraction being the problem not the speed and power of the recoil return due to friction and the bottle necked case. This problem as in the Heckler and Kock was then addressed by grooving the chambers to allow the gases to extract the empty case.
The case, if loaded to high pressure, it would assist if it was almost straight in its outside form, hardly tapered and not bottle necked, so it will continue to form a gas dam as it moves to the rear, although some bottle-necked pistol cartridges (notably the 7.65 mm Parabellum, the 7.63 mm Mauser, and the 6 5 mm Bergmann) have been successfully used in blowback weapons. With large cartridges the case must be short and tough and thick at the head to slide easily back through the chamber while the pressure is still high, and to withstand the high pressure while not entirely supported by the block and the rear of the chamber walls as most blow backs get ignition from the fixed firing pin slightly prior to being fully chambered. So far as known the heaviest c rifle cartridge that has been commercially successfully used in such a mechanism is the .401 Winchester automatic cartridge, which is a short, stubby one with a straight case, and firing a 200 grain bullet at M.V. 2,140 f.s. As might be supposed this rifle has a chunky, breech-heavy feel because of the heavy weight of the breechblock, the weight being added in the form of a heavy bar of steel inside the forearm.
This mechanism has been particularly successful with the .22 Long Rifle rim fire lubricated cartridge, the pressure of which is relatively very low. (Ten Tons per sq inch instead of 19 for centre fire calibres) The .22 case is not strong, but the lubrication prevents its sticking in the chamber. That is why only lubricated .22 cartridges are recommended for use in semi- automatic firearm a fact forgotten mainly in Australia as licences for them are very difficult to get. Many pistol shooter who use .22 semi -autos have problems with different brands of .22 ammunition due to the lack of lubrication or the fact that they rarely clean them and have a massive build up of lubrication in the breech which prevents the bolt closing correctly.
Simple blowback actions are timed by regulating the weight of the breech block and the strength of the counter recoil spring, and this must be done within rather close limits for the cartridge to be used. When regulated or timed for a certain cartridge, if a lighter loading of that cartridge be used, or a reduced load, the action may fail to eject the fired case, and the breech block may have to be retracted by hand. Too much pressure, on the other hand, may expand the case so it clings so tightly to the chamber walls that there is a failure to extract. Generally speaking, fast burning powders are better in blowback actions than slow burning or progressive powders.
The simple blowback has proved to be a very suitable system for the .22 Long Rifle cartridge. We have a number of very reliable self loading .22 ‘s with this type of action, and they seldom give any trouble when kept clean and used only with cartridges having lubricated bullets. Some of them can be used equally well with either regular or high speed cartridges, and others are timed only for the high speed cartridge. The latter will also usually function perfectly with the regular velocity cartridge except perhaps in very cold weather. When there is any trouble with these .22 automatics it is likely to be with the magazine feed, particularly with detachable box magazines.
One precaution should be exercised in using a .22 self-loading rifle. Do not fire it so fast or so continuously that the barrel gets very hot, for the barrel is then liable to lead and perhaps one or more bullets may eventually stick in the bore, which is almost certain to ruin the barrel. (No playing machine guns) Also, cleaning a leaded bore is a difficult and tedious operation. So, treat the little .22 automatic as a rifle and not as a bullet sprayer many are very accurate.

Thoughts for the Week.
Holy Christmas before the Holy War.
It seems hypocritical to wish all our readers a very Merry Christmas and a Happy New Year, even though I genuinely believe in that sentiment. As for only a fortnight the Christmas spirit inspires many people to try a little harder for others rather than themselves. I have Christmas Carols playing in the back ground and our beautiful Christmas tree is lit up in lounge, we have been feasting already at many functions from organisations that we are associated with. Good Will to all Men Throughout the World. Yet the Men on both sides of the earth are planning to exterminate the other half. The world is hurtling at an ever step-up speed into its next world war cataclysm.
History tell us this one will affect or kill proportionally 3 to 4 times more people than World War Two. The only remedy that our world leaders can offer for addressing the economic melt down is ‘War’.
There is no real Peace.
It is an Enigma within an Enigma when the media start shouting, “We have to decide to all live in peace together, or we decide to all die in war together”, as is in past history and the situation in the world today, when a religious group decides to die in war together, the balance of the population who we presume have decided to live in peace together have to kill all the religious group who wish to die in war together. So the peacemakers have to exterminate to gain peace. The war becomes the publicity war to win the moral high ground, so both sides can claim to there own people that the other ogre started it and they are only finishing it so we can all live in peace.The American and allies will pull out of Afghanistan due to the Peace movement in the West, the Middle East and North Korea will view this as a sign of weakness and beat the War Drum. ‘Thesis’ verses ‘Anti Thesis’ leads to ‘Synthesis’ which is the result that those who pay both sides will capitalise on. We will be the meat in the sandwich.
“Chief among the spoils of victory is the privilege of writing the history.” Mark Alexander All the above media games can be contained and minimalised until the powers that control both sides decide that the world needs a revision and the economic growth of war. They orchestrate the casting of the net and boom the world economies and then brake them to bits then capitalise on the government attempts at recovery, then when that runs thin and the publicity swings against them they go to stage three and provoke the big war which will cause massive investment in every country, destroy huge resources that will have to be re-built even their investments in insurance will be saved as all the shipping sinking and infrastructure losses will not be paid out as the exemption for acts of war will come into effect.
“War is the health of the State. It automatically sets in motion throughout society these irresistible forces for uniformity, for passionate cooperation with the government in coercing into obedience the minority groups and individuals which lack the larger herd sense.” Randolph Bourne
The macabre dance began over two years ago, the little wars and Wiki leaks are only to practice and test equipment and idea’s for the big wars. Science, technology and production capacity will decide the winners, the sand has been thrown into the air and no one human, at this point can predict which countries will end up on, on which side. History has again shown us that the countries who stay out of it and get involved at the later stages are the ones that benefit the most from the victory. The winner that fight it from beginning to the end are still losers as they are worn out and have expended their best of there generations and wealth. So enjoy the festive season and only at some future date, remember this paragraph when you watch the world falling apart on the six o clock news. At that time a lot of the issues that we are all so concerned about now, will seem so inconsequential and meaningless. Only the big principles, the huge moral dilemma’s like where is our next meal coming from will matter, at lease we will be able to remember the good times, So lets all make the best of it, visit our families, take the time, spend that time with people that are important to us, eat drink and be merry for none of us know ‘for whom the bell tolls’.
The above warnings are not new and quotes on the subject are prolific its just the timing, as unfortunately history repeats and repeats again. Here are some samples of quotes that are tools that can be put to good use as they may encourage others to think.
“Beware of the leader, who strikes the war drum in order to transfer the citizens into patriotic glow, patriotism is indeed a double-sided sword. It makes the blood so boldly, like it constricts the intellect. And if the striking of the war drum reached a fever pitch height and the blood is boiling and hating, and the intellect is dismissed, the leader doesn’t need to reject the citizens rights. The citizens, caught by anxiety and blinded through patriotism, will subordinate all their rights to the leader and this even with happy courage. Why do I know that? I know it, because this is, what I did. And I am Gaius Julius Cäesar“.
“False is the idea of utility that sacrifices a thousand real advantages for one imaginary or trifling inconvenience; that would take fire from men because it burns, and water because one may drown in it; that has no remedy for evils except destruction. The laws that forbid the carrying of arms are laws of such a nature. They disarm only those who are neither inclined nor determined to commit crimes. Can it be supposed that those who have the courage to violate the most sacred laws of humanity, the most important of the code, will respect the less important and arbitrary ones, which can be violated with ease and impunity, and which, if strictly obeyed, would put an end to personal liberty… and subject innocent persons to all the vexations that the guilty alone ought to suffer? Such laws make things worse for the assaulted and better for the assailants; they serve rather to encourage than to prevent homicides, for an unarmed man may be attacked with greater confidence than an armed man. They ought to be designated as laws not preventive but fearful of crimes, produced by the tumultuous impression of a few isolated facts, and not by thoughtful consideration of the inconveniences and advantages of a universal decree.”Cesare Beccaria
Finally for those that have been intimidated by some Australian shooting Associations that beg their members not include personal security as a reason for owning firearms in their letter to their members of parliament. Sort of inhibiting the freedom of speech by the people paid to help them. This quote is the one that says it all and should provoke the most thought about this whole subject.
“Is your life worth protecting?
If so, whose responsibility is it to protect it? …
How can you rightfully ask another human being
to risk his life to protect yours,
when you will assume no responsibility yourself?“
Jeffrey R. Snyder
Think of that when your loved ones lie dying and your waiting for a public servant to come to protect your family.

Without a Chornograph to give you a known velocity, shooting is all just guess work. There are only two known facts available to a shooter, the hole it makes in the target and its speed. (Pressure guns are not available to us mere mortals) You cannot test, your rifle and ammunition by how much noise it makes or how hard it kick’s you. Get a chronograph, they have never been any cheaper for this quality and if you don’t do it now they will be dearer when you want one next. Then you will be kicking yourself harder than a .600 Nitro Express. They fold up really compact to take to the range, open them up shoot throught the wires and the light meters will give you a print out on the little screen. They fit onto nearly every camera tripod.

UNDERSTANDING RELOADING AMMUNITION
Continued form Edition 47 BALL POWDER
Ball powder, developed before WWII by Winchester-Western, is a relative newcomer to the field. It was used in vast quantities during WWII, the Korean War and Viet Nam. It is a the standard powder for loading 7.62mm and 5.56mm. (.223) military ball ammunition, as well as Winchester’s large range of commercial ammunition.
In appearance, ball powder greatly resembles fine shot. It is in the form of tiny solid spheres which are not highly uniform in diameter. It will also be encountered in the form of spheres which have been passed between rollers to flatten them to varying degrees. For the last fifty years Olin /Winchester have marketed rifle, pistol and shotshell powders making them available to the hand loader. All are produced by Winchester-Western which is, incidentally, the sole United States manufacturer of this type of powder. Other Ball powders are produced in many other countries, such as China and Korea which follow the same process and results and I would presume that Olin has had some share in setting up the plants and of course sharing the profits.
The chief advantage of ball powder is that it can normally be processed from start to finish in less than forty hours. Quite a difference from the fifteen days of other types. Test lots have been completed in as little as twelve to eighteen hours, but such high-speed production has not yet been made entirely satisfactory. Ball powder also has the advantage of metering and flowing very uniformly through loading machines. This feature is especially useful for the hand loader as his powder measure has nowhere near the power of the commercial loaders machinery which has no difficulties in shearing the tubular or log type powders without losing uniformity of the load. Many hand loaders powder measures hesitate as they shear a tubular log powder and this hesitation reduces accuracy of the charge.
Manufacture of ball powder begins with the nitrocellulose in the already discussed slurry stage where additional water is introduced. Purification (recovery of residual nitric and sulphuric acids) is speeded up and accomplished in less than eight hours. At this point the thin slurry is mixed with emyl acetate and introduced to a larger distillation unit. If a double base powder is desired, nitroglycerine can be added, or a straight single base propellant can be produced just as easily. Normally some nitro is added.
Nitrocellulose in the slurry combines with the emyl acetate (solvent) to form a lacquer. Since it is not soluble in water, and is also lighter than water, it rises to the surface of the water in the still. The mixture is then agitated by paddles at a predetermined rate. This action breaks the lacquer into an emulsion. Stirring speed controls the size of the lacquer bubbles produced. Agitation stops when the mix is in the proper state and a colloid is added to form a film over the lacquer globules and prevent them from rejoining to form a liquid.
Hardening, the globules settle to the bottom of the still where they are impregnated (still under water) with the desired amount of nitroglycerine. The wet powder is then pulled from the still and fed on a continuous belt through infra-red drying ovens. It is dry in an hour. The now dry spherical powder is coated with deterrent and graphite in the usual manner, then screened to eliminate those balls grossly over or undersize. The rejected screenings are easily salvaged by combining them with solvent, to be put through the process again.
After testing and blending the screened powder, it is ready for packing, to be shipped to the loading plants. Quite a difference from the long, drawn-out process of producing grained and tubular powders.
As can be seen from the foregoing pages, the manufacture of smokeless powder is no small task. It requires millions of dollars worth of tools, facilities and real estate. Even when done under the most rigidly controlled conditions, accidents and fires are not uncommon. In view of this it is not hard to imagine what would happen if an individual tried to do it in his basement shop with aid of one of those formulas sold through magazine advertisements. Before you ask the question, I’ll answer it from the perspective of a person who has spent time in the special burns ward of a famous hospital, as a patient. “Don’t”, under any circumstances, try to make propellent powder. If any of this information has kindled an interest in manufacture, go to a local University and do a degree in Chemical Engineering and you should find no problem finding employment in the legitimate Explosive industry.
This is the last article on Powder, next edition we will be discussing Bullets.
