The primary reason that I like the WSM's and I suppose other short mags is that I can move away from the belted designs as they are wrong for reloading.
The orginal topic was on the marketing of these cartridges and their velocities. So far I see no increase in velocity with the 7mm WSM that I have over my records that I have on the 7mm Rem Mag in terms of relative case capacities. In terms of pressure I note that the chamber on my M 70 is very smooth thus case sticking on extraction might be less. Other chambers in the past have varied from very smooth to rough however.
There is a comment above that the brass is so much better today? I don't understand the specifics of that comment?
