Is this rust in my bore? Notice the small brown patch to the right and just down from centre. There are several of these spots inside the muzzle which can be seen with the naked eye.Attachment 205330

best you clean it pronto.....and leave it with light coat of light oil..like 3n1/sewing machine oil....or the likes of break free CLP.....
pic is too blurry to say
kind of looks like a gravel road!
what calibre is it?
it looks like it could be copper? you definitely need to fire that rifle more haha.
It’s a 6.5mm.
Could it be some kind of copper fouling?
I smell neglect? Or corrosion..
Usually copper is laid down in longer streaks but if it's the early stages, could be a short one like that. Either way, the bigger question is Why was it left uncleaned?
Did you store it with a suppressor attached.....?
Is that a rifle barrel ?
As for why it's uncleaned. I've been cleaning about every 50 rounds. The last clean was about a month ago. There is just too much contradictory information about cleaning out there.
The suppressor is always removed after use.
Yes, it's a rifle barrel.
For sure it's rust......put a dry patch through and if it is brown there is no doubt. Problem with rust pitting is that there will always now be a layer of rust at the bottom of the pit and that will attract moisture and more rust......you are going to have to change your cleaning regime regardless of what the "contradictory information" says.
Probably a good lesson about which information to rely on....!
Ideally, the bore should be smooth and shiny and the rifling edges square and sharp. If you have a chance to compare yours with a new barrel I think you will see the difference. I would suggest an immediate "deep clean" starting with carbon remover and a cloth patch followed by copper solvent and a bronze brush. I think you could expect to take a good half hour of repeated cleaning before you know if there is any irreparable damage to the bore. Then again, at the end of the day, if it shots to your satisfaction don't worry about it.
This is why I always put an oily patch down my rifles after cleaning them and putting them away never had any issues with rust. I also clean them every time I use them, not full on bore scrub and copper clean but patch with your chosen solvent till patches come out clean then oily patch and wipe down inside and out plus bolt. This is just my regime and it works for me.
I copper clean when needed ie: when I can see it.
I have a mate that shoots competition and he copper cleans a carbon cleans every single time, my rifles shoot as good as his :yaeh am not durnk:
certainly looks like rust and a bad case of corrosion - water getting in ?? or stored in really damp environment - not cleaned after firing ?? personally I think your cleaning regime has failed that barrel - there is a difference between protection and overcleaning - always remember oils coat - solvents pentetrate -- its entirely possible to put a coat of oil over rust and metallic fouling -there's nothing wrong with putting a kind solvent such as hoppes no9 (petroleum based) thru barrel on rag after taking rifle out for day - remove next day and replace with something like Remington oil - but thats simple preventative - dont take to barrell with a steel brush ( only ever bronze ) and harsh solvent ( ammonia based ) that's were the conflicting cleaning info comes from - prevention is better than cure -if I take my rifle out and dont fire it I put a thin coat of breakfree thru barrell that night to get rid of any moisture then dry rag next day - once home dry rag and rem oil -if I have fired it then hoppes no 9 -rarely do I use a bronze brush and even then sparingly - but your barrel needs some serious attention -remove stock and give barrel a good coating inside of hoppes no 9 or other metallic solvent - leave overnight -dry rag - then bronze brush ( likely 10 -12 strokes)and solvent -dry rags - more solvent overnight -dry rag - now what does that rag look like - brown thats rust coming out -green thats mettalic fouling coming out - keep doing the process until dry rags come out same colour as solvent -you tube has some great videos on barrel care - yours may even need more harsh methods such as brushing out with a soft abbrasive like ajax -
Does it shoot ?
I clean after every shoot, and jb bore polish every box of reloaded rounds
Still seems to. I'll keep using it till it doesn't.
as some have said on the forum the acid test is what does it shoot like - if its acceptable then just use it -if the severe corrosion is only muzzle end then perhaps a little of barrel and recrown job - I can see a reasonable rifling edge from the last photo so all may not be lost -but solvent solvent solvent cant beat it -I have always carried a pull thru out in the scrub and if I suspect moisture may have got in then a dry rag thru - when I was culling we ran our 308 barrels with a very very thin trace of oil in barrel - did not effect accuracy- but with our .222 or .270 no way one can do that -
Not that I know much about this but I wonder if abut of JBs bore paste or Autosol would shine it up a bit. Ive got a mint Parker hale that had a patch of rust just inside the muzzle when I bought it. I polished the shit out of it and it shoots mint. Mine had been stored for that long the recoil pad was crumbling and perished and obviously it had been a bit damp at the muzzle.
More importantly, does it still shoot well?
My 308 barrel got a rust spot in it about 25 years ago when I spent a week in shite wet weather in a tiny tent in the Kaimanawas. Had given it a clean and oil the last time I had used it, and I left on the trip with it still oiled but it still rusted.
Now whenever I leave it for a long time, despite whatever anti corrosion brew I store it with, it'll come out brown with the first pull through prior to doing a resight in before heading off on a hunt.
It still shoots 19mm groups.:thumbsup:
Problem with rust pitting in the bore is it will cause fouling (particularly copper) after a few shots which is detrimental to accuracy.....OK if the shots are few, but a competition barrel shooting strings is toast if it is pitted....! And as @XR500 noted it will continue to rust despite having oil on it.
One could try and convert the rust (iron oxide) to iron phosphate by treating with phosphoric acid, but that will only stop further rusting, not fouling.....!
It really needs to be fully cleaned back to clean metal and then assessed properly - a bore scope through the thing not just by eye at the muzzle. Quite often you can find areas against the lands where there is a deep skinny crevice which is very much less than ideal. As others have suggested, it would pay to have a good look at storage and use and see where the improvements can be made as something that often happens at times like this is the owner goes back out the other way and starts doing damage to the borein an attempt to stop any further damage...
JBs or Autosol will make a barrel very "shiny" for someone looking down the bore with their naked eye but will do nothing for proper corrosion patches. It takes prolonged scrubbing with either abrasive to cut even a tenth of a thou off the surface and corrosion pits would be over a thou deep. Most lands are only 2-4 thou high so you'd need to chop out all the rifling to fully get rid of significant corrosion divots.
Thanks fir the advice so far.
There’s definitely a moisture problem in the safe. Damp air and big temperature changes. I’ve bought some desiccants to help the problem. What has everyone found to be the best way to mitigate humidity/moisture in their safes?
If there is an issue with corrosion and/or minor pitting, wap a bore brush through it and a dry patch and then shoot the thing. Give it a good workout with the cheapest ammo your can source - a good hundy rounds is a start. Take it to the range and do with it what god and nature intended, you won't hurt it. After that, fully clean it and then see what it looks like. More often than not, a lot of the stuff we see by the naked eye doesn't survive a decent workout.
I shoot BP rifles with lead projectiles, the barrel starts with rifling goes bald and finished with a bit more rifling. We shoot off hand and accuracy seems to stay near enough for short range gongs :D
Silica gel.
Buy some autosol metal polish
Put a we bit on a clean patch and run it up and down 30-40 times
Wont remove the pitting but it will give the barrel a very light lap i do it every 500 rounds or so
Just to remove any tiny Imperfections also do it to a new barrel before shooting for the 1st time
Make sure you get all the autosol out of the barrel
Use it often, that way there is no chance for the rust to build up.
Keep an eye on the buy sell, a good barrel may come up and not break the bank.
