Re: .308 brass and large primers
AR10T, a little tighter chamber and I was running LC brass. Velocities were a little
wild, 2559 to 2616, 9/16 group , one shot came in at 2503 and opened it up to
1 1/8. I just shot a round robin looking for a new load. Highest speeds without pressure signs were 2688 with 42 grains of powder. A looser chamber will drop
pressures and speed significantly.
Just a thought, if you are running 308 instead of nato loads, that may be your
problem.
