Just me, but I'd stay way the hell away from the WSM...
Care to expound?
In a similar rifle, the WSM provides much more felt recoil.. It's also more finicky to get to feed right... I had a customer who was a yuge M70 fan.. Had a bunch, shot 'em all, a LOT.. He bought a M70 in .300 WSM.. Went to his bench, shot once, packed it up and brought it to me and said, (and I quote) " Put a muzzle brake on this sumbish. It's the only rifle I ever shot that knocked my hat off when I pulled the trigger."
'Nuff said right there..
