Dear submoa, my 270 win has only 22" barrel. With AB 140gr, BC.432 starting vel 2950, at 650yds, with 200yds sight in, it would need 13.43" dial adjustment, terminal vel 1669fps very iffy expansion
Where as 260 Rem with 26"-27" barrel with Amax 140gr BC .585 starting vel 2850fps, at 650 yds, would need 12.52" dial adjustment, terminal vel 1889fps assured expansion.
For 270win, I've opted 140gr Nosler AB, instead of Nosler 130gr Nos PT, to give it better BC in this equation. The short barrel is a handicap. For 260 Rem, I can specify twist to suit long Amax's requirement.
