308 Ammo in 7.62x51 AR10? was created by territo
Just upgraded from my 1968 Colt AR15 SP1 (never selling)
to a new Armalite AR10 A4.

Will this AR10 eat standard 308 Win.-150 grain rifle loads?
I have bulk boxes of 308 range loads for my Model 70.

Or do I need specific 7.62x51mm NATO?
There are slight case differences.

You'll be good to go using .308 out of your AR10. On Armalite's website it lists the caliber as .308/7.62. Congrats on the purchase, BTW. I'm sure you'll enjoy it.

Leb is correct...an AR-10 will EAT both...but for optimum performance...I would stay in the 168gr range...use the 150 for plinking and "I don't care about pin point shots" shooting....as well as the brass for reloading.... ;)
