I have 2 257wbys and different bbl lengths, a 24" and a 26"
i was at dick284's and we put the same ammo through each gun and it measured eggzactly 100fps less
Dick what was that equation that multiplys velocity by bullet weight???
257mag...100gr x 3600fps=360000
270.........130gr x 3100fps=403000
45-70......400gr x 1700fps=680000
