I have been considering doing this but have not done so yet. I want to take a 9mm Luger case and size it in my Mak dies. Then load it with about 3.1 grs of Bullseye... and of course shoot it. I know that I can put a .364 Mak bullet in 9mm case and it will chamber. I am just wondering about pressure. Reason for this is laziness. Not so many reloadable Mak cases around. I cut down 9 Lugers now and it involves considerable time. Also my CZ 82 and my Makarov throw the cases so far i usually don't retrieve more than 60%. Anyone have any thoughts?
