My dad has the .300 Remington Ultra Mag. We sight in at 3' ' high at 100yds. We shoot 180 Trophy-Bonded bear claw hand-reloaded shells with 97 grains Alliant Reloader 25 powder. the gun will scare you after shooting a deer at 150 yards, the exit hole will amaze you. We use it from javelina to elk. It works great with a Nikon scope for those 500 yd. desert shots.
