The firearm thread

[jrandom]

Anyone in the South Auckland area have any contacts for a couple of "citizens of reliable standing" to conduct pest destruction on their behalf?

Any size considered from mice to goats and pigs, the old 30-30 dont mind much.

Join your local branch of the NZ Deerstalkers Association. Most branches arrange monthly hunts.

Otherwise, put some legwork in and knock on farmers' doors in whatever rural area takes your fancy. Often farmers with wild goats and pigs on their property are happy to let in hunters who introduce themselves personally and hunt at arranged times. I have a couple of guys myself, up north, that I contacted that way, who I remain on very friendly terms with.

It's amazing what a bit of politeness and the occasional bottle of wine dropped off at someone's place will achieve.

Someone else.

I have access to a milling machine, but thought rather that milling all the grooves out it may be better to drill holes of varying widths on the verticle grooves.

Turn it into a muzzle brake that will aid in controlling flip.

As in magna porting.

Any idea why AK47 muzzle-brakes are set at an angle??

I have my theories but some fact would help prove/disprove these theories.

Not too sure so I googled the Magna Port company and found this

"
Integrated Chambers providing a more effective method of releasing gases.
Exhaust chambers with an opposite twist to ensure our brake stays tight.
A forward angle directs sound pressure away from the shooter "



In my own personal opinion (feel free to prove me wrong) I feel that these muzle brakes are designed to comply, as much as possible, with Newton's law of motion. ie For every action there is an equal and opposite reaction.

The gases that follow a bullet , and propell it, down the barrel are directed off at such an angle so as to reduce muzzle flip and the twist of the firearm. So if you draw a picture of the muzzle brake concerned, plot the direction of the ports and mark the direction the gases would follow, then draw an arrow in the opposite direction you would get a good idea of which action the designer's were trying to cobbat.

Not too good at explaining this, hope it helps.

SD,

I carried on searching and found this.

"The recoil of a gun severely interferes with the accuracy of firing at a target, particularly when using hand-held guns under rapid fire conditions, because the recoil of the gun tends to cause the muzzle to kick in a direction that depends largely upon the configuration of its stock, i.e., the wooden or metal part below the axis of the barrel. For example, a ground mobile antiaircraft or antitank gun will tend to kick up, lifting the gun carriage off the ground and thus cause it to change position in azimuth and/or elevation. Similarly, a hand-held gun, such as a pistol or rifle, will tend to kick up and often to one side, generally to the side away from the person holding the gun, making rapid semiautomatic fire at a target with accuracy of all but the first round impossible. Consequently, it is common practice to use two hands on the gun, including a pistol, but it is seldom that the person firing the gun is capable of absorbing the recoil equally in both arms, particularly a pistol, and so the gun will tend to kick to one side, even in the case of a rifle, unless held with the aid of some sturdy support to stabilize the gun barrel during recoil, not only because of the stock configuration but also because of the unsymmetrical disposition of the person's body relative to the gun. In an automatic weapon, this recoil problem is more severe since the barrel will kick incrementally with each firing cycle causing the gun to "walk" up and away from the target. "

Goes into a lot more detail

I suspected much the same.
Not only is the muzzle 'brake'? cut at an angle leaving th ebottomhalf longer than th etop but it's on a left-hand thread and a spring-loaded 'lock' postitons it so that it faces the top to the left. (i.e. at first glance it looks like somebody has unscrewed it a 1/4 turn from where it looks like it should be).

I wonder if that is to asist right handed shooters (the majority) as conceivably it would direct the muzzle downwards and to the left.

Any thoughts?

It has been a long time and I am having a hard time visualising the muzzle brake of an AK,

As to it being for a right hander, it could be.

Any one who is familiar with Col Colts single actions would have realised that it seems to be set up for a left hander to load. With the loading gate on the right it is positively awkward to load.

I have always speculated as to wether or not Samuel Colt was a left hander. This would make sense.

Watched a doco about the AK and Mr Kalashnikov was a right hander.

A lot of fire arms have a definite bias. The M16 is a real pain for a leftie unless modified the ejected hot casings will inpact upon the right cheek of a leftie.

From memory of firing the AK in full auto I do remeber the thing climbing vertical and leftwards. (I'm a right hander).

Which way does the rifling twist? The ejection port is on the right. Both these will have an impact on the direction the rifle moves upon firing. Torque effect maybe?

Anyone else have any opinions on this interesting topic? Feel free to join in and add to the wealth of information that seems to be growing in this thread,

Mr

Not sure on the AK, but the big Barret M107 .50 has a huge muzzle brake on it to try and stop the recoil flinging the rifle backwards. Check it out in this vid. http://www.youtube.com/watch?v=TWJp14tkBlU Newtons law again.

Mr

I have found the present version of the M16 suited a lefty even more than a right hander.
I can change mags, use the safety and operate the bolt-lock even easier than most right handers.
And if it jams or 'stove-pipes' I can see it as my right eye has a good view of the ejection-port.

Re the rifling of the AK - I'll have to wait until I have it out again to see.

I recently bought myself a new air rifle to dispatch the rabbits that my cats have become too bloody well-fed and lazy to kill themselves. I now have a .22 Weihrauch HW80 with a Tasco 6-24x40 scope. This rifle replaces my .177 Webley Vulcan, which has been an excellent tool for rabbits and possums at fairly close range. The Weihrauch has impressive power and accuracy at the longer range where the Webley ran out of guts.

Who has some rabbit recipes they're willing to share?

[Delerium]

Thats a VERY nice weapon. Definately man sized and isnt cheap, but very nice.

[ManDownUnder]

... I seem to have stumbled across a tasco 6-24 x 42 myself...

Now to get it back from the US of A LOL... God bless eBay! US$60 for it... new in box!

French Rabbit.

Place rabbit pieces on oven dish then coat liberally with Dijon mustard.
Season with salt & pepper on top of mustard.
Cut bacon into “matchstick” size pieces and place on top.
Add dry white wine.
Roast for 1hr @ 180 degrees.
Remove pieces from dish then add cream into tray to form sauce.
Stir until sauce thickens.
Pour over top and serve.

Jeez that sounds flash, I've always just lobbed them in the camp oven with 1/2 can beer, onion, some garlic, chilie and a tin of tomatoes. Cook for about 4 slow cans of beer and they taste bloody good with some rice.

What about a the NZDF's Steyr where the ejection port can be swapped left or right? Wonder how much this play on the design of the rifle...

[Mr Merde]

This weekend just past I felt the need to make noise and waste powder and lead.

I picked up a few of my rifles and trotted off accross the garden fence to the range.

Sighted in my .22 rifle again. I keep changing ammo and need to do this occasionaly.

Next I burnt powder in my M1 carbine. Love that rifle. Was going to load up a few hundred rounds but I broke the decapping pin in my dies and no spares. In the end I went through about 100 shots just playing around.

Third an finally I let loose with my 30-30. This little baby is going to a new home so I thought to deplete the ammo I had avaailable for it.

All in all a fun day.

Set up some permanent targets, Old real estate signsmake great back boards.

To anyone trying to get accurate with a rifle or pistol, try the following.

Once you have sighted the firearm in go out and sjhoot at a totally white target. No aiming point. Try and keep all your actions the same and try for a group. Easier to say than do.

Those targets with the lovely black spot helps you pull your aim in quite a lot. When you dont have a natural point of aim it is 10 times harder to keep in a group.

Try it.

Have fun
