Discoloration in barrel / cleaning

[Oldbloke]

I think you will find that diamond Is ten on The Mohs hardness scale.

Also combustion always produces carbon dioxide, carbon monoxide and water. The stuff in your barrel is none of those, it is carbon particulate. Just saying.

I also spotted those errors. U are correct

I wouldnt take any barrel to hit against a tree that I ever wanted to shoot straight again. They are not as hard as you think. I have worked on them in a lathe and they are pretty soft compared to other metals esp the stainless ones.

So have I, they're lovely steel for machining, but they're tougher than mild.

You need to be careful with everything you push through your barrel even of it is softer than the barrel. You can do considerable damage with a Cotton pull through after a few thousand passes. Cotten is obviously not as hard as steel.

Yep, I rarely use a metal brush, and only occasionally find a nylon brush required. I prefer to let the solvent do the work and just patch it out.

After working my barrel and brushing it a fair bit with a nylon brush, and allowing the sweets to soak for up to 20 minutes I don’t think I am getting anywhere with this removal. Maybe I am more paranoid now than I ever was.

I really am not sure where to go from here, I have used the sweets and put a dry patch through directly after with almost nothing coming out on the patch (including minimal moisture - probably all on the brush rather than in the barrel), then following up with a second patch which comes out looking as clean as it did going in.

I can only assume the barrel at this point is as clean as it’s going to be.

Just go shooting and forget about it.

I have found that one of the specialist copper removers, with a nylon brush, works better than the old Sweets. I use Boretech, and reckon it works very well. A while back I was at a gunsmith, and asked what he used. Boretch copper remover.
