    Cast boolits and silencers?

    Does anybody have experience with running cast boolits through a silencer? I got a silencer for my .45 and 9mm guns, so rather low velocities and was wondering if anybody had experience with shooting cast boolits through a suppressor. My concern is potential lead buildup on the baffles.

    I shoot cast bullets in the 45 ACP through my suppressor. There is lead and lube build up on the baffles. I clean them after every shooting session because it's easier to get the lead/carbon buildup off that way. If it sets too long, it gets very hard to remove w/o scraping. The buildup is very similar to what occurs in a compensator on handguns.

    Try powder coating. I can’t speak to silencers but the Shake N Bake process is stone simple and all my retrieved bullets are still coated even on and in the lands. I use dead soft lead to boot. No hardening but a water dunk straight from the mold.

    Not to immediately get off topic, but I must ask. Dead soft lead is presumably free/nearly free of antimony. Besides simply cooling the boolits for immediate handling what does your water quenching accomplish?

    I shoot very hard cast, PCed, I do clean with a parts washer after each shooting session, especially when the grandsons come and help me with all that surplus ammo. The baffles clean right up when you disassemble the can, as long as you keep up with the maintenance.

    Most pistol caliber suppressors are serviceable, so can be cleaned.
    I used to be anal about cleaning, even did the "dip", but now I just blast & followup with fast fmjs. The dirtier, the quieter. But still need to clean at some point when weight start to build up.
    Juts make sure to grease 'em well after cleaning so baffles & tube are easier to clean.
    I also use my 9mm can for 300BLK without gas checks. YMMV

    many many folks do it here in NZ I did it with a 7.62x39mm and also the .308 HOWEVER I did end up with a very light end baffle strike so was a tad weary afterwards...not quite sure how or why...more than likely suppressor was a little loose?? as it was only the end cap ,the frontmost hole that had tiny deformation I got round file and enlarged it slightly and had no further issues. going up one size baffle hole wouldnt be a silly idea,gives you a bit more wiggle room for any projectile that isnt quite right or a wayward gascheck.

    Haven't shot anything but cast thru an Octane 9. .22 RF/CF, .30 caliber, all rifle, all subsonic. No card wads, gas checks or case fillers. Somewhere around 2,000 rounds to date.

    one think to keep in mind you will get build up, clean very often so it doesn't get seized up. And if you have a rifle rated suppressor most are not user serviceable and you cant take out the baffles, if it was me i would never use lead with that type as you cant clean then out effectively.

    Never in a sealed can! The ones you can take apart and appropriate for pressure, have at it. Like Mr. Gibson they come apart after every trip to prevent build up. One little thing I have been doing for a while that really seems to make life easier for me. Once you get internals clean, latex gloved and rub thin layer of silver anti-seize (which every can owner should have anyway) on every surface internally. Messy, you bet, but tear down is rag wipe, inspect, rub some more on and assemble.

    Interesting. I was just thinking of anti-seize and if it would work that way.

    I wonder if it works on gas pistons as well?
