Smith revolver help

[Lefty Trigger]

Found this today cleaning my new 629 44 Mag. Appears to be metal flaking off inside the barrel, only seems to be in this one spot but they are deep. Gun has less than 300 rounds and has only ever fired light handloads less than 950 FPS using copper plated bullets. Tried calling Smith but I guess they shut down early for the holidays. My local gun smith said he's seen this before with stainless barrels but its rare. Anybody ever see this??

My 686 had that. ended being lead. Good bore brush and a lot of solvent fixed it.

Clean it with a brush , I'm curious what that discoloration is on the barre back by thr near the receiver . It's at 12:00 -10:00 as you pistol is up side down

Its not lead, its actually pits in the metal like its flaking off. You can feel it with a pick. There is also two small places on the barrel crown where the metal has chipped off. I have never seen anything like this before and the more I look at it the more it pisses me off this gun is only 8 months old and has barely been shot.

Crappy picture, trying to hold a small flashlight to see inside the bore better, could be reflection?

Can you take a pick and scrape that stuff in the barrel? Ive seen lead thatll fool you pretty bad. It was from a 44mag shooting those flat nose copper jacketed bullets with the lead tip. Pretty much ironed onto the same spot

Going to take the gun over tomorrow to a better smith with a bore scope so he can take a look. He thinks its lead as well but I just don't know. I have never fired any lead bullets through it so I'm not sure where the lead came from? I'm hoping it is because that would be an easy fix and not have to send it back to Smith.

The lands cut thru the thin copper jacket, exposing lead. Some manufactures use almost pure lead.

Have you shot lead, plated and jacketed at the same outing? Shooting jacketed last may imbed the lead in the barrel. Needing extra cleaning.

You mentioned copper plated rather than jacketed. Plating can rupture easily exposing the lead underneath. Jacket material is much thicker and offers much better protection to the underlying lead. Hopefully, lead fouling is your issue.

The lead I removed from my 686 was a pain in the a$$ to remove. It was embedded welded onto the barrel, but it came off after a lot of brushing and using a dental pick.

Take it from someone who leaded up a lot of Smith barrels with what he thought were hard cast bullets before he learned how to properly alloy his mix and buy you a Lewis lead remover....

Thanks for that link, now that has me wondering if the plated bullets just cant take the 44 mag load even though they are light (under 1000fps). I shoot plated bullets exclusively because of price and easy to get but maybe that might not be the best option,... at least for the 44.

Take an old cleaning brush and wrap it with some copper scouring filaments from a Chore Boy pad. Make sure it is pure copper. Scrub it out. Plated bullets will lead even at low velocities. Best to use hard cast.

Ok you guys was right it is indeed shit in the barrel. He ran borescope in and the barrel looks perfect but has two places in it with "something" fused to the barrel. He cleaned it with a copper remover and he said the patch will turn blue if its copper and this came out! He also said what ever is in there its in there good and is going to take more to get it out. He also suggested the Lewis lead kit so I ordered one for the 44. However he told me that there is indeed damage to the barrel crown but that has noting to do with my other problem wanted to know if the gun was a display model? He's going to recrown the barrel and I can pick it up after Christmas.

I use Choir Boy all the time on my handguns. Just make sure you purchase the original Choir Boy, I think it's the only company making an all copper product. Most I see in the stores are copper plated metal and thats no está bien. Choir Boy may be hard to find because it is the preferred screen material for the crack pipe crowd, so stores are out, or don't stock it because it just gets jacked.

that there is indeed damage to the crown.


.

The pilot used when crowing the muzzle may have caused damage where the copper is getting ripped off the plated bullet?? Or the pilot was copper instead of steel?

Return to factory for repair, Turn around time is long

The crown repair has NOT been done yet and has noting to do with the "stuff" caught in the bore. Both problems were found by me at the same time. He seems to think that the gun was a display model and displayed on a peg hook and it being pulled off and put back on the metal hook has caused the crown issue. The crown damage is at 12 and 6 oclock.
