Default Friend going into minefields

Member of our club bought a ton of 190 gr BTHP 308 bullets for his 700 Rem 308 rifle. This has become a driving force in any rifle he buys and right now he is looking at an SOCOM 16 and a AR 10.

I flat told him to wave off the SOCOM 16 as he is into a minefield of issues but I don't know if a AR10 can sustain 190 gr loads.

Please confirm that 190s are not recommended for either rifle. I want to copy your comments and try to wake some sense into him.

I don't think either rifles gas system can take 190 gr loads. If wrong, hammer me hard.

Thanks.

I do not go over 175s in any of my M14s. Maybe just me, but I would rather be safe than sorry.

Military teams routinely shot 190's on stout loads.

They also had the resources to replace damaged rifles.

Yeah but this dude is wanting to shoot 190s in a SOCOM 16 carbine...that is not a M1A gas system..its a chopped & shortened M1A gas system. I see big problems there.

The gas system on the 16 is the same gas system on the others.

Only the gas lock sight base / muzzle brake combo and threads on the end of the 16.25" barrel are different.


As for the 190s, he can shoot all he wants - at his own risk if he closes the gas valve.

Wouldn't it be okay in the AR system? No op rod to bend.

If going to 190s, I would want an adjust gas plug on the M1A. On the AR I would want an adjustable gas block. Now, having said that. 190s would need as much velocity as possible to stablize. I would want as long a barrel as I could get to give them as much velocity as possible. IMHO, nothing shorter than 20", but preferably longer.

Although no .308 gas guns that I know of were designed to shoot bullets as heavy as 190 grains, I'd say he can probably shoot them in his SOCOM as long as his hand loads do not create excessive chamber pressure. That sounds simple enough, but it would require a reduced load. The 190 grain bullet was designed for long range shooting. Reducing the load and shooting it in a 16 inch barrel completely defeats the bullets intended purpose. Note to that it should be fired in a ten inch twist. The SOCOM has a twelve inch twist... There have also been issues with the new forged bolts in some M1A rifles shedding their lugs with M80 ball ammo. Heavy bullets may tend lead to the same results. Springfield does not warranty their M1A if hand loads are used. Think about that.

ARs don't have the issues that M14s/M1As and Garands have. He can shoot any commercially made ammo in an AR10, or any other AR based 308.
