Cleaning problem

[skip AI]

G'day,

I was ceaning my .257 this arvo and after 2 hrs of cleaning I could not get out this white coloured substance that was in the barrel.
I assume that it is just copper fouling that is showing up white because of the sweets 7.62, I got most of it out but now something wierd is happening.
When I feed my bronze brush through you can feel all the bumps of it hitting the rifling, does this mean my brush has worn out?
I tried another one I had that looks to be a little thicker (not as worn) and got the same result, what is goin on?

TIA

I would suggest that you not use a brass or copper brush with Sweets.

I would highly recommend that you stop using Sweets 7.62 for regular bore cleaning. Even if you do not let the cleaner sit in the bore long, over time you will etch the finish of your bore with this solvent. Just to damn aggressive.

I only use it in worst cases where there is dramatic copper build up.

Also, you need some nylon brushes with this solvent.

Good Shooting!!

Any ideas on the colour (its white like paper)?

There was heaps more when I started and now there is only a great white smudge left, it was not there before I shot the rifle and it seems to be cleaning out.

What about the brush?

What do you reccomend I use instead of sweets?

cheers

If Sweets has ammonia in it and you give it enough time to dry, it will give you a white pasty substance. Patch it out w/a non ammonia solvent and I bet your white goo will go away.

I like either Coppermelt,or Buth's Boreshine and use a nylon brush.Also as mentioned earler Sweets will dry so you will need to use another cleaner such as Hoppes,Buth's Boreshine,Shooters Choice,etc to liquify the sweets inorder to get it out

Thanks for the replies, So you think the sweets has eaten the brushes away enough so when sent down the bore they do not have a thick enough diameter to make contact with both sides of the bore therefore not spinning?
