So I got some great handloads worked up for my 243, 41.5 gr N160 with 95 vld at the lands. 3/8 Moa. What's completely blowing my mind is that with a dirty cold bore, first shot hits 1.5" high. The flowing 5 shot group is 3/8 Moa. Then I do a deep clean an shoot it the next day and first clean cold bore shot is 1.5" low followed by 3/8 Moa 5 shot group. Makes me afraid to take it hunting what do you think?
