My thing is hunting with a muzzleloader; rifle marksmanship is also my thing. Every year i shoot 15,000-40,000 rounds of center fire ammo and am a former amateur benchrest shooter. There are no inaccurate guns in my safes.

Getting accuracy from a muzzleloader is not rocket science. Some of us manage that very well without BH 209, and lots of other spiffy stuff that some folks claim is absolutely required.
