I have been using this powder for a while now and was wondering it is possible to overcharge a load with it to where you could blow your gun up? I just don't see how seeing you can't crush it even with the shell loaded full up to the bottom of the boolit I have never had a problem with it. the calibures I load with it are 45 colt, 44 special and 45/70. anyone blow up a gun when using trail boss?
