You should know that changing barrels/magazine boxes, etc on a Savage takes just a few minutes so you don't need to buy another gun down the road, just rebarrel yours and keep your stock, mods, scope w mounts. What I'm getting at here is that if you eventually want a 300 WM you might get that now and rebarrel to .308 just like Savage used to do with the older 110s. I'll bet you can find a .308 take off barrel for around a hundred bucks, maybe less. If you really want a short action then make sure to get a 300 WSM
version for the CRF, that one can be switched to .308 also if you don't want to load down the WSM.
