Last week I picked up a Burgess Shotgun at a gun show and have some 2.5" 12 gauge black powder shells on order. I am interested in the smokeless loads you mentioned. No mention of them on the B&P website. I am going to call them but wondered about your experience with them. How many have you shot, any signs of problems. I found several other low pressure smokeless 2.5" shells but was told by one manufacturer, Polywad, that they and the industry in general would strongly recomend against using smokelees loads in a Damacus barreled shotgun.
