I have shot them before in several different muzzle loaders with good results, honestly didn't expect any issues with them this time......that's why we verify I guess.

I also have had nothing but success with Powerbelt. All whitetails out east where we could use in-line, Triple Seven pellets, and scopes. Was a 50 cal, 209 primer, 295 gr Powerbelt, and always used max load (150 gr), don't know if that kept things more consistent.
