Chad...Then again. He might not know about BH 209. Now he has options. He got plenty of info on the powders he asked for. I shot T7 and Pyro for years. It works, but i think BH is a better hunting powder. If for no other reason that it doesn't absorb moisture, and if you don't find it more accurate than the other powders. It will be just as accurate. As for being corrosive? I need to see an official test to believe it. Not saying it doesn't, but I need to see it. For me...I get no corrosion.
TNH..The guns that don't have a problem shooting BH. Don't have to use a special primer. My Omega that has a great BP for BH would shoot any primer except the ML primers. The CVA will do the same wit a BH BP.
It's only the guns that don't have great BP's that need the hot primers. Like a CVA with the stock BP.
