RE: 7mm mag vs deer
I've had one since 1997 and is my favorite caliber. I shoot 140 noslers and I don't notice anymore damage to the meat that any other caliber. If you shoot a deer in the butt theirs going to be damage but who is shooting deer in the butts. My longest shot with the 7mm mag was a measured 304 yards and I hit within an inch of where I was aiming. I would be confident out to 400 yards on a no or light wind day. You could make longer shots but thats the longest range I have to practice and the bullet is dropping fast at that point.
