I have, on two occasions now, had the opportunity (!) to fire 44-40 BP loaded rounds that I had dumped into my vibratory cleaner with ceramic beads and soapy water and vibrated for several hours for one and overnight for the other. Each one fired when given the chance. I no longer think of sealant when loading!
Yes, they were lead boolits (200 gr Big Lube) and crimped with the Lee crimp die.
