    I just got a Savage 11 in .300 WSM. The rifle has the detachable box magazine. I just started my first .300 WSM loads tonight with new, prepped Winchester brass, Ramshot Hunter, Remington 9 1/2 magnum primers and Nosler Custom Competition 175gr bullets. The magazine length will accommodate 2.992". But the chamber throat will only allow 2.855". It's usually the other way around - OAL limited by the magazine capacity. Has anyone else run into this where the chamber throat requires the seating depth to be shorter than the magazine length? I may eventually lengthen the throat so I can seat the bullets nearer magazine length and increase my powder capacity.

    Before spending the money, first figure out where it shoots best. Might not have to do it.
