Re: .260 and 130 grain berger
Jump'em
Right at lands is worst case unless you cull bullets by base to ogive. Bergers are very consistant but if you want to be right at lands, still need to cull by length.
Start at 0.040", work back in 0.030" increments, and best OAL will jump out at you.
0.040", 0.070", 0.100" of jump, 5 rds at each length, test'em at 300 yds.
