Letters to Editor, Re Those (Shooting Industry) about to Die

Dear Mr . Owen,
 
I have just read your article re Those about to Die etc. and congratulate you on your article, like yourself I must admit to being politically incorrect re. shooting sports, and am proud of it. I left the UK 49 years ago because I was thoroughly pee’d off with the Metropolitan Constabulary refusing to issue me  with a firearm cert. for a single shot .22 that I needed for vermin control on a private property when I had been carting a .303 rifle to represent my RAF Squadron at various rifle comps. for a two year period without running amok, I was told that the police did not want ” idiots running round the streets with rifles “. First thing I did when I got to Mt Gambier was to buy three firearms with no problems, …

Bulletin March 19, 2009

Subject: Just ran across your site – interesting

HAS YOUR HANDGUN TRAINING SET YOU UP TO BE KILLED?       
 
Hello,
 
Here is a link to an article that you may wish to add to your blog/e-newsletter/site-articles, or even publish in paper form.

UNSAFE AT ANY DISTANCE – THE FAILURE OF POLICE HANDGUN TRAINING.

INTRODUCTION:

Hopefully, you will find this article of interest.

Here are some reasons why you should read/share it.

1. It may lead to a reduction in Police casualties, and in a reduction of dollars now spent for naught on learning shooting methods that are neither practical nor effective for self defense use. It also poses the conundrum: whether or not all “non street” Police need to carry a firearm.

2. The same benefits that can accrue to …

Letters To the Editor :- Early Stainless Steel ?? Barrels

Bulletin March 18, 2009

Letter to the Editor

Sent: Monday, March 02, 2009 3:25 PM
1. Subject: Stainless Steel barrels.
Hi Ron.
I have been interested in stainless steels for barrels for some time, since acquiring a Model 1904 rifle with it, see photo

Photo 018 Winchester Model 1904 #707136 - Left Side-Stainless Steel Barrel a
I note your Bulletin No 11 that you advised:
“For several years prior to 1930 the Winchester Repeating Arms Company supplied a “stainless” steel to a limited extent. It was really not a steel but rather a high chrome iron, its approximate composition being chromium 13 percent, carbon 0.10 percent, and copper 1.50 percent. Certain intricate heat treatment was necessary to make it both machinable and rust proof. It could not be successfully blued and was copper plated outside and then subjected to a treatment which turned the copper black. High cost of production and the advent of non-corrosive ammunition led to its discontinuance. “
Can you please advise the …

FIREARMS SAFETY DEPENDS ON YOU!

Free Stuff September 22, 2008

INTRODUCTION

From the time a firearm is grasped in the hand, the shooter becomes a part of a system over which the shooter has complete control. The shooter is the only part of the system that can make a gun safe – or unsafe.

Hunting and target shooting are among the safest of all sports. This study is intended to make them even safer by re-emphasizing and reaffirming the basics of safe gun handling and storage and by reminding each individual shooter that he or she is the key to firearms safety.

You can help meet this responsibility by constantly stressing safety when handling firearms, especially to children and non-shooters. Newcomers in particular must be closely supervised when handling firearms with which they may not be acquainted. Don’t be timid when it comes to gun safety. It you observe anyone violating any safety precautions, you have an obligation to suggest …

Keyhole Shots

Free Stuff September 21, 2008

Keyhole Shots

An injury to the muzzle of a rifle can cause shots to keyhole. This condition is most likely to occur in rifles cleaned from the muzzle, but may be due to accident, such as striking the muzzle against any metal.
A very small burr on the muzzle crown can make the bullets unstable in flight.

Anything that reduces the rotations per second may cause a bullet to tip. Low bullet velocity may reduce the spin enough to cause this effect. A long bullet requires more spin than a short one, so that too long a bullet for the twist or too slow a twist for the bullet may cause tipping. Excessive wear of the rifling or too loose a fit of the bullet in the barrel may cause the bullet to fail to take the full spin required.
As barrel erosion progresses, the portion of the barrel just …

A Loaded Muzzle Loader

Free Stuff September 21, 2008

A Loaded Muzzle Loader

“I didn’t know it was loaded”

“I didn’t know it was loaded” is the stock expression used by those who are rudely awakened by an explosion when they pull the trigger of a any loaded firearm. Muzzle loading firearms seem to be even more prevalent in this due to the lack of observation of the chamber. They seem to be always presumed empty.

An old muzzle loader is more likely to be loaded than would at first be thought. One reason lies in its slowness of loading. This resulted in many muzzle loaders being kept loaded habitually, as the only way of keeping them ready for use. Another reason lies in the difficulty of unloading, which caused many users to put off that tedious operation and finally forget it.
It was usual to leave the cap (or priming charge, depending on the type of ignition) off …

Ammunition is Effected by Temperature

Free Stuff September 14, 2008

Ammunition is Effected by Temperature

Temperature has a marked effect on both velocity and pressure. Factory ammunition is, as a rule, rather conservatively loaded so that no danger will result even under extremes of temperature.
Twenty years ago a large quantity of 6.5 x 55 ammunition was imported into Australia, (I was responsible for a few million round of it) It was 139 grain FMJ brass case with a berdan primer I suspect made by Norma in Sweden. In normal conditions it was excellent ammunition. (I once shot a five shot.500 inch group at 200m with it). There were reports that it had blown up guns, on investigation this was not the same ammunition only the same calibre. It got everybody talking though.

A southern importer had imported blank ammunition in this calibre and had replaced the wooden blank projectiles with 140 grain soft points. This would not have been …

Exploding Barrel Blockages

Free Stuff September 12, 2008

Exploding Barrel Blockages

Bore Blockages

Obstructions in a firearm barrel are almost certain to damage the barrel on firing.
The kind and amount of damage depend on location of the obstruction, on its mass (weight), and on the type and thickness of the barrel. A very great variety of results are possible. I have known of them killing the shooter next on the firing line, and only giving the owner of the firearm a sore shoulder. This is the extreme but it can and does happen.

An obstruction close in front of the cartridge in the chamber has the effect of increasing the chamber pressure. An obstruction in the middle or forward part of the barrel produces a local injury.
The action of an obstruction does not depend on trapping air. Experiments with coils of wire and other open obstructions resulted in damage about the same as solid obstructions of …

Glossary For Optics

Free Stuff May 22, 2008

Optical Glossary

Achromatic
A lens classed as achromatic has been formulated to be free of chromatic aberration, which causes colour fringing. An achromatic lens, or achromat, achieves identical focus with light rays of two different colours.

Apochromatic
Apochromatic lenses are corrected to bring all three primary colours to the same focus.

Astigmatism
Aberration in a lens or optical system that makes lines oriented in certain directions less sharply focussed than lines running in other directions. Astigmatism also occurs in the human eye. A typical astigmatic effect would be to see the vertical lines on a sheet of graph paper sharply while seeing the horizontal lines less clearly, or vice versa.

Bell
In scope sights with ends flared to accommodate large-diameter ocular or objective lenses, the oversized lens housings are referred to as bells, as in ocular bell or objective bell.

Binocular Collimation
