I'm thinking way "out of the box" here. I know of the occurances of detonation when using reduced loads with very slow burning powder, so I pack in in!!! I have an abundance of Mil. surplus 50BMG powder. I've used it numerous times in my .375AI for fire forming/plinking. I fill the case, seat a 270 Hornady and have fun. Velocity is only a little over 1800fps, but it's scarey accurate. Leaves some unburned powder in the bore, but all seems well. So, here's the question - What's the thoughts on a 300 gr. cast,full case,hot primer, heavy crimp for a "plinking" load in a 460 S&W. Death Wish or should it work? I need to burn some of this powder!! memtb
