I started powder coating a few years ago. The limits are still not known. A few years ago most people would say to treat it as a substitute for lube and nothing more.
Now most of us know it's far more than that. I'm shooting a lot softer alloy than I was ever able to with lube. I don't use gas checks on any straight wall pistol boolits. My 500 S&W load produces over 30k psi and my un checked PC base does not get pressure cut and does not paint the interior of my muzzle brake with lead spray like it did shooting a much milder load using the same boolits lubed.
I've shot the Lee 55gr .225 un-checked and PCed at around 2000 fps with several loads that will all cycle an AR-15 and observed no boolit related fouling. (It's a shame this boolit relies on the gas check for over half of it's bearing surface).
I've disassembled all of my seating dies previously used for seating lubed boolits and cleaned all of the built up dried up lube out of them. Same goes for my boolit sizing dies.
I guess you see where this is heading:
The answer is NO !!!!! I'm not ever going back to lubing. If I didn't have so much bore butter I'd probably be PCing my muzzleloader boolits too.
I honestly had to go look to see what BLL was. I think it's great. Maybe it will make it eaiser to find someone who I can dump these 6 bottles of A-Lox on. LOL
