I had an uncle I once saw grab a runnaway steer by the tail and throw it to the ground. He was 6'5" tall and hunted with a 20ga remington pump (precursor to the ithaca 37). Also saw him show a tres'passer the line fence by the scruff of the neck and the seat of the pants. The fellow was off the property when he landed. I was told, by his brother, as well as his oldest friend, that he,in his younger days, wrestled a wounded buck to the ground and killed it with a borrowed knife. His rifle was a remington mod.14 in 30 remington. He killed the largest buck I've see taken, a 13 point measureing 24" through the curve. He shot both guns just as they came from Montgomery Ward.
I'm 5'8" so shortened stocks don't bother me no matter the gauge. I most often carry a 20ga with a 13&3/4" LOP, but I really like 12 gauge guns. It's a macho thing.

Best to you,
Kurt
