Hi Pal, well they are different, but not by much. I would say stay with .308,and there is mountains of load info out there, and you can use military brass. I have been reloading, for a few years, for bolt guns and M1As( I got got my first AR10, building another). You will find, that you have to trim your brass, for Semi-Autos, once you get OAL, (Over All Length) You got it. Lots of Deals on Surplus Bullets( Pulled) Brass, ect. out there. .308 the way to for sure, I would also look into his big brother, the .300 Win. Mag. You will like him too. Later vince.

Thanks for the info Vince.looks like the 308 would be the way to go.have not started reloading yet,but i am collecting reloading equipment.would it be possible to build a 300 on the ar 10 platform ?what parts would be different.could i use the same upper .what about the bolt,buffer,and other things.could be possible if the 308 comes out well. thanks again, ronnie.

I pretty sure you need an AR-30 or equivalent for 300 Winchester Magnum. The cartridge is much larger than a .308

Noveske Rifle Works makes some of the finest, most accurate Armalite .308 barrels out there.  <thumbsup>

Hi again, yeah I meant .300 win mag in a bolt gun.  The Bullets are .308 dia. Powder is different, in 300 win mag, much slower, and alot of it. later vince.

Yeah I figured as much, just want to be sure others understand  : )

Of course a 300 win mag AR would be cool

Hi, I just checked Armalite's Web Site, and they offer a 338 federal. Specs on that round are a little better than a 308, but Iam not sure, given  all the 308 reloading stuff out there, if worth it. later vince.

go figure ,good old armalite.development along with the army marksmanship unit .it started as a 300 wsm but soon was changed to the 300.saum do to some areas of the 300 wsm case being to thin.armalite will list it as instock but will be a limited run.saw this article at shooting times mags website.did not notice any release dates or when the article was published.them lower is a regular ar10,but the upper and parts have been modified .
