308 vs 300win mag

[XC700116]

so a muzzle brake dosent bring the 300 back down to 308 levels of recoil?

The right brake makes them very easy to shoot, but everyone around you isn't going to like it.

APA Fat Bastard would be the brake I'd run on a 300 WM. It's big, but it works wonderfully.

As to 300 WSM, I'd build one off a long action so you can mag feed the longer high BC bullets and not sacrifice case capacity.

For the OP, the key words I see is First Precision Rifle go with the 308, or something like a 260, 6.5 CM ect.
