i shoot a sbe in iowa, where you can only use shot gun. i have tried many slugs and like the brenneke k.o. slug. 2 3/4 - 1 oz. they shoot great out of my sbe well over 100 yards. with a great knock down power. i to am a seasoned slug shooter, and by far this slug is the best that i have found , for the reasonable price. so if you are looking for a slug for your shot gun buy a box of each one and try it till you find the one you like the best. thats the best thing to do.
