Would anybody have the correct length of the .257 110 grain TGK and the correct length of the plastic tip please? I just measured the .257 110 ELD-X and got 1.228" and 0.14" respectively which is different than what appears on JBM bullet length list. I want to see if G1 bc is effected at 29.0 Hg and 29.92 Hg in a 10 twist. Thanks.
