RE: BLR Caliber
Becasue if he is wanting the ballistics of a magnum he would be better off with the 24 inch tube that comes in the 300 Win mag and the 7mm Rem mag vs. the 22 inch tube that comes with the wsm's.
I know everyone has their personal preferances as to what they want in a gun but IMHO if I feel the need for a magnum then I want the barrel length so the magnum will perform like it is suppose to. I don't see much point in puting a magnum in anything less than a 24" barrel.
