I did buy a package of plastic beads, but have yet to use them. I generally don't cast during the hot months unless I start running out of bullets, and I practically haven't been shooting at all so far this year. My workload ramped up considerably, and I either seem to be either really busy, or totally exhausted. It looks like it's time for me to take my life back. Anyway, I have supplies & materials backlogged around here for experimentation. Powdercoating figures pretty prominently in some of it.
At a recent gun show I went looking for tumblers, my elderly "big" Lyman tumbler has fallen ill, and I went looking for another older version of it, primarily because the older Lyman tumblers were awesome, but the newer tumblers are rather uninspiring, to say the least. I found a guy with a fairly new Thumlers vibratory tumbler, and bought it for $50.00, and started negotiating with the guy on another tumbler he had on the table. This one is an old design called a Vibratec, it uses a non-rotating vibratory motor, and uses plastic tubs to hold media & brass. This one will get plastic beads & lead bullets for powdercoating. I share some others concerns about the potential for bullet damage (especially bases) with conventional tumblers. The price ended up being perfect for me. The guy thought my project was interesting, and simply gave me the Vibratec. I had one once before that was much smaller than this one, which is huge. The plastic bucket you see in the pic is a 1 gallon ice cream bucket. This is going to be interesting, to say the least.
Brad, since you have all that excellent data & research from your 44 mag SRH with various bullets, I'd like to suggest you start there with your powdercoating. With the issues you've overcome with it, and especially with the Accurate mold design, I think it would be fascinating to see what effect powdercoating would have on that project.
