I too had a .54 and sold it a couple of years back. It shot T/C maxi hunters really well, but not round balls. I shot one small mulie buck at a dead run from about 30 feet and it swung just like a little double side-by-side on quail. Dropped him like a rock, but it was probably the luckiest shot (and probably one of my poorest choice) shots ever. It was a great little gun in the brush with that short barrel.
