Well I now have a 375 Ruger and I also have a set of 338 RCM dies as I use the seater to seat 338-284 shells so I am set up to form 338-375 brass and seat bullets.

Besides the belt, what is the benefit of running a 338-375 Ruger vs a 338 WM. As I understand it the powder capacity of a 338-375 Ruger is between a 338 WM and a 338 Rum/Edge.

What sort of velocities are you getting compared to a 338 Rum/Edge ??
