i'll be honest i had no idea or thought that i would have to check to see if you could shoot loose powder out of a mz rifle i have shot white rifles all my hunting life so the thought never entered my mind ! i didn't know a mz rifle company needs to advertise there gun shoots loose powder either that's the dumbest thing iv'e ever heard ! my whole point of starting this thread is that i bought a brand new rifle and even though i can probably shoot loose powder with the current bp i can't get the one i should be using is that sad ?
