I have shot trap, grouse, beer cans, trees, pizza boxes and just generally made loud noises with them.
They are great thought my pump and my friends pump action too, but my buddy prefers the federal equivilent sheels from canadian tire (I think) for his 11-87 semi auto.. this shell isn't as reliable on cycling the action and ejecting in that gun.
Other than that they work just fine.
everybody loves the $22 100 pack of 12 gauge shells.
