What is the trigger like on the shotgun? How does it balance? What distance will you be shooting? My Encore Muzzle loader with 90grains of BH209, Hornady 250 grain bullets, black sabots, Zeiss 3-9 x 36MC diavari will put 3 under 2 inches at 100 yards, but I don't shoot it a lot. The BH209 cleans up without water and does smoke but not as much. I used 777 for years and it was awful as was pyrodex. BH209 is the way to go. The Encore kills with one shot, and hits where I aim. The balance is forward making it easy to hit with off hand. I have killed only 14 deer with a muzzle loader and none with a slug gun so I am not an expert on slug guns. I used buckshot as a kid. If I had it to do over again I would buy the CVA model break open gun that takes rifle barrels as well over the Encore.
