I'm running a Wilson 1-7 twist with a wylde chamber, using AR-COMP, CCI450 primers and LC (match prepped) brass.
I tried loads from 22.0 - 23.0 grains in .2gr increments (5 round groups) and I had some success with nodes at 22.4 and 22.6gr. With these nodes I'd have three rounds coming in at .75MOA and then two wild fliers. The other nodes were more of patterns than groups. This was all shot off the bench @ 200 yards, using optics.
From what I read, these are supposed to be fairly jump tolerant and I was seating them at .020 off the lands. I'm going to try another batch with .010, .030 and .040 to see if it makes a difference.
One more try and then I'm going back to Berger 82's
