Building a 50 BMG

iconfig
Thanks for "wasting" your time responding to a troll. I DO appreciate you taking your valuable time trying to educate him.
I figured if I quit feeding him, he would move on so was prepared to let this thread die.

It seems that "Chris" greenpasture has some axe to grind with me, not sure why and frankly don't care. As you too have noticed he seems to have a really high response count racked up in ATRS attacks.

Possibly now if he is done we can get back on with what this thread was started for before yet another thread gets locked for troll abuse.

Correct me if I'm wrong Rick, but is the AT50 built on a custom in-house action?

The current 50cal breech load action is built inhouse but I am phasing it out in favor of a giant Rem 700 style action both in single shot and repeater.
I do not expect these to be in production until early to mid 2011 as we are currently tied up in making actions for 308 Win and 338 Lapua boltfaced calibers. We are` working hard to have the short actions finished to unveil at the Calgary gun show next weekend ( April 2/3) .
The breech loaders were made of 4140, but the new line of actions will all be 15-5 stainless with 4140 CM bolts to keep galling to a minimum.

sweet! :d
 
Our last 50 on a Barnard GP went out the door at $5400 plus tax and shipping. This is an absolute match grade ready to shoot (you add the scope) rifle. It is single shot (but why would you need a repeater???). Try to beat it!

Are these with an alloy chassis type stock?

I shot one from the boys at ABC bullets and it was one sweet shooting rig.

Rick, that new action sounds wonderful. Look forward to the details.

I too have not quite figured out why a repeater is required in a 50 cal rifle unless you are in combat, and then the gun is supplied.:confused:

And not to mention that $15 per round match ammo as well. You wouldn't have to shoot 400 rounds before your ammo cost would eclipse the that of the rifle.

I basically want a repeater for the look of it , something about that huge box magazine turns me on, which is the same reason I want the big muzzle brake on it too. Also it would be nice to be different then everyone else.

Ian with your 50 cal in that stock with the cheek piece that goes up , can you open the bolt on that Bernard action with the cheek piece elevated?

I own a repeater as well as a few single shots but only used the mag once in the repeater. Having the tips of the Amax bullets deformed from slamming forward inside the mag because of recoil seemed to me to be rather counterproductive to accuracy. Now I use the single shot follower in that rifle.

To me the greatest "look cool factor" is tiny groupings at outrageous distances.

Wanting to be different I certainly understand, look cool I also understand, but believe it is good to also understand some of the possible downsides of "look cool" versus "works better".
Every magazine I have looked into using is too short for optimal OAL when using bullets like the Amax or Lapua.

We will be employing the AI mag for our repeater for ease of access.

The most important part is to make a truly informed decision when making a "significantly expensive purchase".

Slamming forward ? What kind of repeater do you have ? One you made your self ?
 
The cheek piece is not adjustable but is removable to remove the bolt. We have done some with a saddle cheek piece but customers have said it is high enough without it.

Being the exclusive distributor for North America of AMSD firearms I own a Nemesis rifle, which is a repeater.
Under recoil ammo in most larger caliber rifles will be slammed forward inside the mag.( Newtons law of physics IIRC)
Softer tipped (exposed lead or aluminum) bullets is more prone to tip deformation. The recent trend towards polycarbonate bullet tips is 1 of the ways bullet mmanufacturers are using to help reduce this from happening.
In a 50 there are no where near as many bullet choices however. The only projectiles I have found that seem to be virtually immune to tip deformation is the FMJs, whch tend to not be as accuarate as the match bullets are, but they were never designed for match accuracy, just reliable feeding at high volume from a full auto.

For that kind of money you would think they would come up with a better clip design . Thats very dissapointing.
 
Don't know about any .50 magazines, but it is common for magazines to have ribs pressed into the sides to engage the shoulders of the rounds to prevent inertial shifting with consequent nose damage.
