I normally shoot 2-3/4" 00 buckshot, which I do fine with. I've done 2-3/4" slugs, which were a bit rough. This is the first time I fired a 3" magnum shell in the boomstick. With a load that loud and with that much kick, it would be difficult to get back on target and take a second shot (assuming the first one didn't kill or otherwise scare away the target). I'd prefer to be able to get all 7 shots off with a less powerful load.
