[QUOTE="Mikecr, post: 409044, member: 1521"] As an example: 1/2 of a grain off from a 190smk = .002change in G1BC = .5"@1000yds[.048moa].. The MV change of ~4fps counters this almost exactly though.. That is, if the bullet is low by 1/2gr, it's BC drops, but it's MV rises to counter. So nothing to account for there really. As far as any assumed dimensional changes with weight variance,, well, is it so wise to assume anything? And you cannot measure bearing surface variance without first qualifying the ogive radius(your datum). That is, unless you just want to assume that as well.. More wasted efforts.. Anyway, I highly doubt that bullet weight consistency has contributed to any BR shooters success, or failures. [/QUOTE]
