I'll second what was said above. I wouldn't wish a sub 8 lb magnum on my worst enemy haha. Even short action calibers and lighter long actions will bite in a rifle under say 7 lbs.

I personally owned a Kimber Hunter in 308 and I honestly didn't enjoy that gun at all. Even if it was for the specific purpose of mountain hunting, if you a gun isn't fun to shoot, you won't practice with it and you aren't doing your quarry any justice.

That said the recoil wasn't horrible so if you're going light, go short action. The only way I'd consider a light magnum would be to have it braked.

That's just my 2 cents.
