Dennisinaz,
Appreciate your info. I'm now working on Berger 140's for hunting. I did the Berger suggestion on optimal jump,
shooting three shot groups at .01, .05, .09, and .13 jump. Seemed that I had my best groups at .05, and .13. I decided to do a "jump ladder" from the idea of a powder progression ladder, looking for clusters. Problem, you have to account for each bullet for it to work. I shot at 200 yds, hoping for more spread to make it easier to tell what was going on. I loaded from .01 to .18 in .01 increments all with my best Vv 165 load. Many were hitting so close, the 80X spotting scope couldn't differentiate. Made a bunch of 4 wheeler trips to the target. Bottom line, had two clusters, around .05 and around .13. Currious as to why two clusters and which one to use. At least the data appears reproduceable.
Any ideas or suggestions?
