Pitting on end of barrel,

[Birdshot]

 

[Birdshot]

Hello folks I made the mistake of having my gun in storage for a year with the moderator on and has resulted in some pitting......the barrel is stainless steel, could the pitting get worse? Does pitting spread?

Would you like me to post a picture of the muzzle of my .243 to make you feel better?

Aye ......go for it

Does it shoot a good group? If so, clean it after use and don't store it with the moderator on.

Yeah I can shoot good groups at 100 meters

I don't think you need worry too much.

Marked in red - don't worry about it
Marked in yellow - if there is pitting here you may have issues. Do a few five round groups to see if there is any considerable expansion of the group from what you would expect. If there is an issue, it might be worth chopping the barrel back, recrowning and rethreading, and then don't leave the suppressor on again when stored.

I don't think you've got much to worry about. Mine's looked like this for as long as I've owned it, and it shoots fine.
(I think you can still see hacksaw marks from when the barrel must've had an inch or so lopped of the end at some point in the past!)


I head shoot all my park deer with it, up to about 120 yards, and foxes up to around 200 yards, and it continues to do the job without fuss.

Thanks for the reply......just before taking the picture I rubbed the end of the barrel with autosol and a scotch brute pad I think that could be some of the pad in the barrel

I thought it might!

When it looks like this is the time to start worrying.

No the pitting will not spread without the means of water carrying acidic elements from combustion. Water vapour is produced on firing, condenses in the can and later provides a humid environment etc.

That muzzle looks to have hard carbon stuck to it and it might possibly chip off.
