I bought a .308 when they first came out. It has always shot MOA or better with the 150 grain Federals I use. I have a Ruger American Ranch Rifle in 7.62x39. It uses the Ruger Mini 30 magazines, and is bullet proof. I load for that rifle, and the groups at 100 yards hover right around an inch, give or take. I am using Sierra's 125 grain Pro Hunter .311 bullet, and 25.5 grains of IMR 4198.
My other Ranch Rifle is a .223, using a rotary magazine. I get an inch or less all day long with my load using the Winchester 64 grain SP over H335 powder.
zero issues with any of the three.
