Suppressors are the whole reason I delved into powder coating my cast bullets. I have built most of my own, but have a commercial .45 ACP can which is "sealed" and cannot be cleaned, so I built one of my own that could be, prior to me learning how to powder coat. I used to keep careful tabs of the weight of my 300 BLK and .45 form 1 cans and pull them apart when they'd gained about 2 ounces, scraped the huge crumbly chunks of lead off of the baffles and from the inside of the spacers, recoat in silicone grease, and reassemble. Royal pain, and I had to do it about every 500-1000 rounds. Keep in mind I had very little lead in my AR gas systems (some in the gas rings), and the bores were lead-free, it's just the nature of shooting plain based lead bullets that some atomized dust will always come out with the bullet. .22LR is the WORST at leading up a can, notice most of the commercial ones are engineered to be easy to service.
Since I started powder coating, I get zero leading in my cans. Now have about 3500 more rounds (all powder coated) in m BLK can and only a little carbon and a few flecks of powder are inside.
