I have a Savage 10 FCP-K law enforcement rifle chambered in .308 winchester.
Lets hear some opinions on using 7.62x51 Nato in this rifle.

It's all the same in a bolt-action.

Go for it.

If there is a problem, it would be using .308 in a semi-auto 7.62 rifle.

Yeah that is what I figured.
I also have a Armalite AR10 A4 and even though the roll mark saids 7.62 the manual does say you can use either 7.62 or .308 in there AR 10's.

It's more a potential problem with M1A's.

The commercial .308 uses softer primers then mil-spec, and slam-fire damage/blow-up is possible in a M-14 type action.

At the worst, all an AR-10 can do is doubling. The bolt carrier/rotating bolt design prevents firing pin contact until the bolt is locked shut.

you'll lose some accuracy and a little muzzle velocity. other than that, blast away.

In a bolt gun it's fine. Marine scout/snipers use 7.62 reloads in rifles stamped .308. The main thing is consistency.

I did shoot some .308 in an M1A stamped 7.62, and when it got warm I had same failures to eject.

Good info here, my M1A standard is a preban stamped 7.62mm on the heel i'll be careful with .308.

10 years ago I had my Savage 10FP Tactical freeze up after the first shot I ever took with it. I was using South African 7.62. I couldn't turn the bolt or anything. After getting it back from Savage, there was a note with it saying "don't use military ammo."

I would love to shoot NATO stuff through it, but I'd rather not have a defunct gun again...especially since it's no longer under waranty.

I've read that the chamber presure is higher on .308 than it is on 7.62x51mm. Does anyone shoot .308 in older FAL's, M1A's, etc? Any problems?
