My Black Diamond never did like a powder charge over 110gr. When i bought the rifle back in 1999, i used 100gr. pyrodex pellets and 240gr. T/C Mag Express bullet/sabot with a Federal 209a primer. I never did experiment with loads back then- i really didn't know any better. I was young and inexperienced and didn't know anybody else that shot muzzleloaders lol. Shot with the open fiber optic sights, too- no scope back then. Before i bought the Triumph a couple years ago i was using 110gr. Triple Seven ffg, 250gr. Shockwaves and Winchester Triple 7 primers in the Black Diamond. I was averaging 1 3/4" groups at 100 yds. using a 3-9x40 scope. Good shooting to you all.
