Fouling

I have a 22-250 improved target rifle with a stainless barrel. It wouldn't have had more than 700 rounds through it. So far it has only had powder fouling in the bore. No matter what type of bullets I use. Recently I started using winchester ball powder and hornady v-max projectiles. Now It takes me all night to remove all of the copper fouling.(of which I never used to get)In the end there is just that little bit of green left on the patch which gives me trouble.
I don't know if anyone has had this problem before but any help you can give me would be great. Thanks.

Try Butch's bore shine! Use a bronze brush if necessary! Good Luck

magnum - What type of cleaner(s) are you using? Some bullets tend to be softer than others and thus increase fouling. With 700 rounds through the barrel, you should have a very smooth bore. There is not much you can do to avoid fouling other than switching bullets.

Not sure how you are cleaning but, you guys (Aussies) invented one of the best copper solvents in the world - Sweets. While Butches is great, Sweets is the best for removing stubborn fouling. I would suggest that you try it to clean your barrel. Make sure you follow directions to the letter and use a high quality preservative oil like BreakFree when finished. It will take no time at all to safely remove copper.

after i got a bore scope i stopped leaveing
copper removeing solvents in the bore for more than 10min at a time. after 48hrs you can see pitting. worst fouling barrel i have is a 223 sendaro. i use a bronze brush and sweets 7.62 with about 20 passes then a few patches of butch's bore shine.

My suspicion (sp) is that your barrel is starting to show a little fire-cracking; microscopic cracks in the metal. The copper is pressed inside these cracks, and is the devil himself trying to get out.

A possible solution is to get some J.B's, Iosso, USP bore paste or Flitz metal polish, and give the bore a good scrubbing/polishing. If you do have cracking, this will remove some of it, and will reduce the "embedding" of the copper.

FWIW, the only sign of copper I would worry about is an accuracy drop-off. HTH, Dutch.

I've tried almost all of 'em and Barnes CR-10 is the only one I've found that works when used as directed on the label. My worst-fouling barrel, a pitted pre-war Winchester, comes clean with two applications when used exactly as directed.

That, or a Foul Out III if you have the time.

Hi magnum, just keep cleaning.
Have fun!
