RE: 7mm. Rem Mag VS. .300 Win. Mag.....RECOIL????
I have a Browning A-Bolt Stalker in 7mm Rem Mag, and one of my hunting buddies has a Browning A-Bolt Stalker in 300 Win Mag. I sight in his gun for him every year, and I can tell you the 300 has more of a sharper "hit" to the shoulder, and the 7mm has more of a steady "push" in recoil. Both have the same muzzle blast, and the same muzzle flip.
I've never shot a Remington bigger than 30-06, so I can't help ya out much. Other than the Remington 30-06 was alot easier on my shoulder than a Savage, or Ruger M77 30-06.
