RE: muzzleloading for turkeys
I am fairly new to the muzzle loading thing too. I'm useing a Thompson Center 12 Gauge New Englander with a HS Strut .675 Choke tube. What I have worked up so far is 90 grains of Goex ffg a knight plastic shot cup and 2 oz of 6 shot.
It patterns rather well. It's good out to 35 yards. I am going to do more tweeking yet before season.
