I just compared my magazine length (3.39" max OAL) to the OAL I need to touch the lands in a new to me 300 Win Mag model 116 and came up with a 0.230" jump required.
Is this typical with anyone else? It seems like an awful lot of freebore.
The max length to fit the magazine is the same as a Win M70 (300WM) that I have.
