Don't enjoy my light Remington 870 pump shotgun with 3 inch Slugger Magnum slugs. Those whack like a mule kick.

I can shoot the same slugs or Brenneke 3 Inch Magnums (Black Magic's) out of 12 gauge Silvio Brignoli all day long, though.

Proves the point again... It is not neccesarily the round, the caliber, the gauge... It is the gun.
