Re: fn spr
One of the good things about the Winchester/FN short mag actions is that they are longer, and have a longer magazine than the comparable remington or tikka rifles. You can take advantage of this when handloading, and seat the bullets much further out.
I have a Winchester Coyote in 300 WSM, and it is my do-everything rifle. It doesn't have the CRF bolt SPR has, but the action is similar. I load 200 grain bullets to a little over 2800fps with a 19 1/2" barrel.
The 300 WSM is really a great round, and if you handload, the only additional cost is the 40%-50% extra powder you use. The recoil takes a lot of practice to get used to. Proper use of a sling helps, as does a brake, if you plan on always wearing good earpro.
