I have the Dtech 1:8 Oly SUM 20" with comp. The load I'm tuning on is 23.9gr of AA2015 (.1 below pub max) behind a 55gr VMax with Win primers. My avg vel is 3123 fps, SD 13.89 Temp was mid 60s and a bit of wind blowing 10-15 from every direction. This is a 5 shot group at .6 and if I take out the top hole (trigger operator error I'm sure) it trims the group by quite a bit. Seating was 2.25" 24.0 the groups opend up a little along with high teens SD. I'm going drop the charge .1 and play with crimp to see if I can get the SD down.
