Re: 510 Allen Magnum finished after some long nights this weekend...

B1G_BORE,

I will admit I am pretty happy with my muzzle brakes!!! No need for recoil any more for this kid, I guess my question is why put up with it when you do not have to??

Factory triggers, well, lets just say they get tuned before a single round is every put down the barrel. But as far as factory rifles go, as a smith I walk into a gun shop and see a row of parts on the racks, not rifles!!! [img]/ubbthreads/images/graemlins/grin.gif[/img]

I set my rifle up to shoot standard BMG ammo. That said, being the type of feller I am, if someone from California wants a 510 Allen Magnum, I will simply chamber the barrel so that its headspace is 10 to 20 thou shorter then the standard BMG case. That way you could not take a standard 50 BMG round and chamber it but it would still be a simple proceedure to run a 50 BMG case up into a 510 AM FL die and set the shoulder back to the proper amount for the correct crush fit for fireforming brass.

There are ways around Kalifornia Laws!!!

My 50 Allen Tactical will also be marketed to the Kali crowd a well which will offer basically 50BMG performance in a totally differnet case design.

The Ma in law was not home but she is pretty used to muzzle blast living around me!!

For the heavy pills I am just sticking with the 1-15 twist. From the projections I have seen, this twist should be adiquate for all the bullets we want to test. From reading on testing of fast twist barrel in the 50 BMG, the advantage was not really there over a standard twist barrel. That said, some have played with 1-12 twist barrels with very good results so if I have to go to a faster twist, I may go with a 1-12 but thats as fast as I will ever go.

Any 50 BMG receiver will work great for the 510 Allen Mag. I used the AR-50 because it was a Full length botl action which I could accurize fully, it has a floating bolt head which I really like for accuracy, its a 3 lug design which I also like.

It uses Rem 700 triggers, always a good thing!! It has a VERY positive safety design.

The bedding design is as good as anything out there right out of the box with no bedding at all. And finally it just feels good to shoot. Nice adjustable cheek piece for any height of scope. Adjustable recoil pad location.

While it definately has a military look to it, I do like the lines of the rifle.

One other feature is that this receiver is WAY longer then the 50 BMG requires, In fact it was designed to be used with the Russian version of the 50 which is significantly larger then the 50 BMG. If I can find a reliable soruce of brass for the 50 Russian, there will be a new 50 cal round from APS, basically the same design but on the significantly larger case.

That all depends on if this larger case design proves worth while that is. Getting cases is the only real issue so if you know anyone out there that can get me 50 Russian cases, let me know!!

Good Shooting!!

Buffalobob,

Forgot to answer your question about the bipod.

Basically I will just fit it with new mounting pins to take up the slack in the factory system. Pretty loose. I am also going to look into fitting it with some bias springs to help stabilize it for shooting instead of it having the ability to flop easily side to side.

I am also going to look at increasing its range of tilt to make it more usible in the field.

Thanks, I was putting a pod loc on last night for the Harris bipod that will go on the 7AM and was curious as to how much more damage I could do to it [img]/ubbthreads/images/graemlins/grin.gif[/img].
