with the short mags, you can now have both, short/lightweight and velocity.

270WSM
300WSM

you said ranking the next round? ie racking a new round or reloading a 2nd round?

I think you can chamber a new round very fast with either if you wanted to, course a short action with a short bolt rise should be faster than a LA 90 degree. But really does .3 secs vs. .5 secs matter? etc...?

A lot of these guys on hunting shows take 2 minutes to chamber a 2nd round...haha.
