Thread: Short barrel magnum calibres?

Interesting that 7 SAUM has become more popular relative to 7 WSM here than elsewhere, especially the US, despite giving up 80 fps or so to the 7 WSM. As already mentioned, I expect it’s down to neck length.

Shearer is right that short length necks aren’t necessarily a problem, but I would rather have a 7 SAUM than a 7 WSM.
