Had a chance yesterday to go out and put my SR through its paces.
SR556, 16" 1:9, Leupold HAMR 4x scope
Midway Dogtown 55gr hollowpoints, ~24.0gr IMR 4064
I didn't label these reloads so the powder charge could be a little off- shame on me and lesson already learned. Anyway, my best group at 100yds was 2.331" center to center. I'm certain that some of it was me, although it would be nice if the barrel was free-floated. Lessons learned for my next build, for sure. It was about 33 degrees and raining the whole time, so I think that may have influenced some of the results. At this point I'm not sure if any more accuracy can be had out of this barrel or not, but we'll see. Only time will tell.
