Another question now that I have a load that shoots well.
45-70 69 gr Goex 2f. 510 grain creedmoor out on the lands, dgl lube.
Temperature about 80 F and 85% humidity.
5 round groups blow tubing, all under 2 moa at 100 yards.
But when I try wiping, the groups double in size immediately, and I get leading.
Is this a lube issue?
