Pinnacle, "burn" vs. "explosive"
Going to Gander Mountain today to get some powder. Hoping they have Pinnacle, cuz I want to try it in my T/C Scout. I looked for Pinnacle at a local sporting goods store but they don't carry it. The guy there said they can't, because they don't have a license to sell explosive powder. He said the Pyrodex they do sell is not considered explosive, because it "burns", but that the Pinnacle "explodes". I told him thanks, but left scratching my head on that one.
Anybody know if he was correct? If so, is Pinnacle going to be safe to shoot in my T/C Scout? I would use 100 grains max (maybe 110), but now I'm wondering about barrel pressures with the Pinnacle, and if I can use it in my Scout.
Any help would really be appreciated. Thanks, Al
