just got done makeing up new load for moose. i am relitively new to muzzelloading. i worked up to 135grains of pyrodexbehind a 300 grain sst. i got a 3 shot group of 5/8th inch at 50yards. i didn't know bp could shoot so good. i wanted to test these bullets to see how well the stayed together, so i shot into a stack of southern yellow pine blocks that has been sitting out for a year. it went through 7", exspanded to 7/8", and waighed 284grains. i am very impressed.
