I liked to use 12g Win AA & Rem RXP hulls loaded up with 1 1/8 oz of shot,1 1/4oz of shot in 4's,5's,6's,7 1/2's with win 540(hs6) it will reach out and touch anything you want.A friend asked me for Win 540 so I explained use HS 6 same powder,this was used with lead shot for skybusting ducks & geese back when that was the way to go.I've used it for grouse,squirrels,mtn quail,bandtailed pigeons,rabbits,pheasants here in the western usa.We won lots of money shoots using Win 540 & Win 571(hs7) over the years.These loads will rock your socks don't need any 3" or 3 1/2" hulls these loads will do the job.
