Compared to the 243 he apparently shoots well with, a 7mm Mag has got a bit more recoil/kick to it. Though I will agree it'snot what I consider a monster, recoil wise, itcan take some getting use to.

Strap that puppy into a shooting vise and see what it'll do group wise. That'll answer a lot of questions. Most weatherby rifles have a 1.5" guarantee using premium ammo.
