RE: .300 ultra mag
Actually I have to agree that the Remington 300 UM is not a gun for the beginner or faint of heart. The felt recoil is 42.6 pounds.
The gun can hurt you if not shouldered correctly with that recoil. I own both the 300 RUM AND THE 338 RUM both in the Sendero models. It is little difference in velocities and little difference in recoil the 338 is 43.4 pounds of felt recoil but they haveunbelievable stopping power at long ranges.
The velocities from the muzzle on each gun do not vary much. The 300 comes in around3480 and the 338 comes in around 3510 but theenergies and trajectories are unreal on either.They are easily some of the flatest shootingand hardest hitting 30 calibers available.
