convert Savage 300 WSM Stagger feed to 6.5 PRC

Has anyone done this? If so did you have to lengthen the box to accommodate cartridge length? Looking at this. My box measures just under 3" Will that be adequate to accommodate the cartridge?

If you have 300WSM brass, I would consider a 7mm or 6.5WSM.

I made an error, it's actually a 7 SAUM, not that it probably makes much difference
