born_2_kill Posted July 15, 2015 Report Share Posted July 15, 2015 (edited) Quick question, what are barrel stones and what do they do? I recently purchased a new gun from a top end gun shop and while looking at it I saw some what looked like to my untrained eye very light pitting, I mentioned this to the chap showing me the gun and he said he would be able to have it removed if I returned within an hour and he would "get his stones to it". I returned and the pitting has 99% gone I can see just one very small pimple which I think used to be where it was. Just a couple of worries - will the pitting return if I care correctly for the gun and has using these stones made my barrels thinner. I paid a fair bit for the gun and know very little about this, hoping it isn't the same as having the barrels bored out when you have extreme pitting, I just want my gun to last me a long time.

CharlesP Posted July 15, 2015 Report Share Posted July 15, 2015 Yes your barrels will be a little thinner. The "stones" will have been used to remove the metal surrounding the pitting. With care your pitting shouldn't return. What is the gun? Quote Link to comment Share on other sites More sharing options...
born_2_kill Posted July 15, 2015 Author Report Share Posted July 15, 2015 AyA #2, the little remaining pimple won't cause me future issues as long I clean the barrels and keep them oiled? Quote Link to comment Share on other sites More sharing options...
Gunman Posted July 15, 2015 Report Share Posted July 15, 2015 (edited) All depends on how much has bee honed out . Even with what appears minor pitting can often take more boring out than you would wish for . [Take it from one who has long experience of this. ] Unless you knew the bore sizes and wall thickness prior to the honing it will be impossible to say .Pitting once in will stay there forever ,it is a matter of scrupulous cleaning to keep it at its present state ,leaving it dirty will give the rust and corrosion a chance to get a "toe hold " in any pits that are there. I should for your own satisfaction have the bore sizes checked against the original proof sizes . Edited July 15, 2015 by Gunman Quote Link to comment Share on other sites More sharing options...
born_2_kill Posted July 15, 2015 Author Report Share Posted July 15, 2015 I phoned the chap up today and asked him about the honing, he said the stones where only used to polish the barrels and would remove very little not even .001 of barrel thickness. He said obviously the barrels would be well within proof and thickness of them is only a concern on much older guns. My main priory is to stop it coming back, don't want my remaining pimple to become anything more. I want the gun to last me a long while. Hence going to a top gun maker such as Elderkin.

bostonmick Posted July 15, 2015 Report Share Posted July 15, 2015 To be honest I would never buy a gun with pitting nomatter what make or what dealer had it.It shows the gun has not been looked after correctly. Just my opinion and everyone is different. Quote Link to comment Share on other sites More sharing options...
born_2_kill Posted July 15, 2015 Author Report Share Posted July 15, 2015 (edited) If he'd have polished it before I got there I'd never know, this could happen to anyone buying a 2nd hand gun, maybe even you in the past? Bet there isnt many 30/40 year old guns that havent had slight pitting thats been taken out at some point...

bostonmick Posted July 15, 2015 Report Share Posted July 15, 2015 At thirty or forty a gun should just about be run in.I have several in the cabinet that have been on the farm since new and some are around 100 years old never had barrels honed been tightened a couple of times but looked after properly.

Zapp Posted July 15, 2015 Report Share Posted July 15, 2015 My hammergun was fine bored in this way a while back. What looked to me like some pretty bad pitting is now completely gone. Quote Link to comment Share on other sites More sharing options...
born_2_kill Posted July 16, 2015 Author Report Share Posted July 16, 2015 Has it stayed away since? Do you leave a coating of oil in your barrels after cleaning? Quote Link to comment Share on other sites More sharing options...
Zapp Posted July 16, 2015 Report Share Posted July 16, 2015 Yes, they have stayed mint since. I clean the gun no different to any of my other shotguns - a few swipes with a lightly oiled boresnake. Quote Link to comment Share on other sites More sharing options...

Moblies Posted July 17, 2015 Report Share Posted July 17, 2015 Keep it clean, lightly oiled and Don't put away wet and it will be fine. consider one of those gun socks off ebay to keep the moisture out when in the cabinet. Quote Link to comment Share on other sites More sharing options...
Gunman Posted July 17, 2015 Report Share Posted July 17, 2015 Goes with out saying always clean the oil out before shooting . Quote Link to comment Share on other sites More sharing options...
born_2_kill Posted July 17, 2015 Author Report Share Posted July 17, 2015 Whats the effect if you don't? Keep it clean, lightly oiled and Don't put away wet and it will be fine. consider one of those gun socks off ebay to keep the moisture out when in the cabinet. Always spend 30 mins cleaning it soon as I get home, put 2 big rugby socks over each end which join in the middle, hopefully all this should keep the barrels tiptop.

browning123 Posted July 17, 2015 Report Share Posted July 17, 2015 If you look after the gun, clean the barrels after use the pimple you are referring to will get no worse. Personally I would never buy a gun with any type of pit/mark in the barrel, but that's my opinion - but I know I'm fussy with my firearms.

born_2_kill Posted July 17, 2015 Author Report Share Posted July 17, 2015 Upon closer inspection (just spent 10 mins looking at it in different lights) I'm not sure it is pitting it looks like a mark left by a cartridge plastic wad, there's a couple of lines and marks I can see that are typically made by wads.

born_2_kill Posted July 17, 2015 Author Report Share Posted July 17, 2015 (edited) Here's some pic of the said mark click for full size As you can see from the first picture and barrels are like black chrome all the way down, nice and shiney (excuse the oil marks in the pics) Edited July 17, 2015 by born_2_kill Quote Link to comment Share on other sites More sharing options...
wymberley Posted July 17, 2015 Report Share Posted July 17, 2015 Pretty sure that that's not pitting - no matter how you clean the barrel, pitting usually - if not always - shows up black in colour. It could be scratches from the stones. Try giving the area a really good scrub wiith a Payne Galway phosphor bronze brush. Really don't think it's 'owt to worry about. Just go out and shoot the pesky thing. Quote Link to comment Share on other sites More sharing options...
born_2_kill Posted July 17, 2015 Author Report Share Posted July 17, 2015 Haha nice one cheers, I need a new brush my old one is well worn maybe why its not cleaning it off, would have thought my looped brush would pick it up though. I will check out the brush you mentioned, many thanks. Quote Link to comment Share on other sites More sharing options...
