[QUOTE="nksmfamjp, post: 1933433, member: 1951"] I used to jump in with an ocw test min to max 5 groups of 5 at 0.030” or mag length. Then after 2 ocw rounds, switch to oal to fine tune. Now I’m trying a 100yd ladder with 0.2 - 0.4 increments. This helps me find pressure point velocity nodes and impact position. I shoot 1 shot per bullseye into 10 bullseyes. It tells me how velocity and impact point are shifting shot to shot....to find a node. At the same time, I shoot another ladder varying oal looking at poi shift and velocity nodes. Then with the best oal, I do a 3 shot ocw test with the best oal and better charge weight nodes. So far this second method is sucking, but I think that is because I tried straightening bullets to improve concentricity. I’m blaming my 1-2” groups on straightening loaded round. So, I’m reshooting these loads. [/QUOTE]
