Which would be the best for a lightweight rifle that would be hard hitting and accurate out to 250 yards or so? How is the factory ammo availability? And, how about reloading? I have a .308 and a 35 Whelen now. The 35 a little on the heavy side (9 lbs with scope) Mauser action. My 308 is a light weight Ruger 77 synthetic. I can make 35 out of 3006 brass, and I think you can make 358 out of 308 brass? I was thinking bear protection while out hunting moose or caribou.
