Rich406 Posted January 16, 2023 Share Posted January 16, 2023 I’ve been shooting an Atlas Artemis this winter. The Artemis has a sight block barrel. I’ve been shooting mostly blue bullets through it. The problem is, I’ve been getting hella lead and coating build up between the barrel crown and the sight block. I’m afraid to really dig at it because I don’t want to damage the barrel crown. anyone have any tips, or experience with this? Link to comment Share on other sites More sharing options...

Typically good to just scrub it through with hopes 9 but I understand sometimes lead can be stubborn. What I did previously was to get about 3-5 rounds of fmj ammo and shot it through the barrel. The FMj projectile tends to squeeze the lead out with it. At least most of it. The flip side of this theory which some say is some lead that remain gets pancaked inside the barrel which might make it tougher to remove (?) I haven't experienced that so far or if there is, its too tiny to notice. But I always thought the FMJ rounds have been very helpful for stubborn lead.

rishii Posted January 16, 2023 Share Posted January 16, 2023 I don’t know if this would help, I spray my comps with kroil after every outing and let it sit until the next time I shoot kroil is a penetrating oil that soften and get under the crud and it blows out the next time I shoot it Link to comment Share on other sites More sharing options...
ltdmstr Posted January 16, 2023 Share Posted January 16, 2023 Maybe try a search for comp cleaning in the open forum. Far as I know, your choices are basically: blast, scrape or scrub. Link to comment Share on other sites More sharing options...
shred Posted January 16, 2023 Share Posted January 16, 2023 Yeah, same problem comp dudes have, but with harder access. I wonder if a piloted crowning tool would work if you were careful not to recut the crown. Link to comment Share on other sites More sharing options...

Use a different powder which doesn't vaporize the coating off of the bullets. If your ammo is "Smoky" then the coating is getting vaporized. For example, Tight Group + Major PF 40 cal coated bullets = MEGA Smoky Link to comment Share on other sites More sharing options...

ltdmstr Posted January 16, 2023 Share Posted January 16, 2023 Not much you can do to prevent it. Powder selection will definitely help minimize it, as will shooting jacketed v plated bullets. But, even with Sport Pistol or N320, you're still going to have build-up over time. It's one of the reasons I'm not a fan of the design. Link to comment Share on other sites More sharing options...
nearsightedgunner Posted January 19, 2023 Share Posted January 19, 2023 Try to switch to plated bullets. The cost maybe a little higher but I don’t believe it will be much. Are you sure its the blue polymer coating you are seeing around your crown or are they carbon deposits? Either way you need a little elbow grease. Try Scottsbrite pad and a good brand barrel cleaner solvent. Patiently rub the deposit with it. Link to comment Share on other sites More sharing options...
lroy Posted January 19, 2023 Share Posted January 19, 2023 Think I remember an Atlas vid of them recommending shooting some plated rounds through it to end your session to help push out s#!t out the barrel/comp. Link to comment Share on other sites More sharing options...

That’s mostly about the barrel itself. the build up I’m talking about is in a gap between the barrel crown and the sight block. You can’t really get at it without scraping on the crown, and I don’t think that’s a good idea. Shooting a jacketed bullet will do nothing for this, in fact it might push more buildup into the gap. what I was really looking for is someone that shoots a nemesis. And their experiences.

Boomstick303 Posted January 19, 2023 Share Posted January 19, 2023 Maybe contact Atlas. Maybe they have seen this on the gun before and can give you the best course of action. Something to try is Peroxidic Acid. Soak the tip in the Peroxidic Acid and try some gentle mechanical means to remove the lead. I have used a Dremel Engraver and Peroxidic Acid with great success on my PCC muzzles. From use of the Engraver where I Dremel one end in the fashion of a chisel of sorts, it does not seem to be scratch the muzzle material, but I would test that before taking it to the crown. Careful with the acid it will flash fumes and is very irritant to the respritory system. Take appropriate precautions when using it. Link to comment Share on other sites More sharing options...
