Found a great load for my 31 inch desert tech,
190 bergers
63.5 H1000.
.080 off the lands
Adg brass
2955.
This netted about a 2.5 inch group at 630 yds.
I believe that's what it was. I also flipped the spring around in the mag. That seemed to have helped alot. I just did a test feed with some 183s and they were fine. I'll have more to test this weekend.
