[QUOTE=mbliss57;139022759]Well I finally got a chance to take my new Ruger SR 762 out . The .308 is just a boss round. I was shooting 168gr HPBT. The rifle jammed after the 1st 7 or 8 rounds. Then again a few rounds later. I turned up the piston pressure setting from 2 to 3 and it was flawless the rest of the afternoon. Compared to an AR15 you definitely know you have been shooting after awhile. QUOTE]
I had the same issues with mine and cranked it up to the 3rd notch using the same ammo. It "seems" to be getting better with time and more reliable in the second setting. However, it still doesn't like the lighter grain (147) ammo and I have to stay on the 3rd setting with those. I'm hoping with time and more shooting it will quit being finicky with any ammo. It IS a great shooter when it's working right.
I also have a Colt 901, CRL-20 and an S&W AR-10, have had zero issues with any of them shooting anything.
You're also right about definitely knowing you've been shooting something with any of them in 308.
