I cleaned my triumph anally last night. Foaming bore cleaner. Wire brush, more bore cleaner, wire brush more bore cleaner patch, patch. Then i looked it over ran some windex down to get a nice shine and see what it look liked. Still alittle dirty more bore cleaner, patches, windex, patch. Looks good so i ran some alchole down it. Looked good and let it dry ran some oil down it. The alchole and oil ran down and came out clean and i mean spottless. SO i put it up and left it. When i got home from school i was looking it over and checking it out. I love that gun by the way. I noticed what looked to be copper or plastic fouling. Looks like little bits of grit or copper. Not sure if it is or not. I am going to go shooting first thing in the morning. Is it ok to leave it or should i run a dry or alcholo patch and see whats in it. Then reclean it if it is copper or powder. Not sure how it could since the alchol and oil came back clean. It was sitting by my walk barrel up could it just be some dust. If it is copper or powder could it have damaged the barrel in a day.

have you been shooting copper plated conicals? Its probably just some plastic.

Shockwave 250s black sabot with a real tight fit.

then its just plastic. The bullet in a sabot will never touch the bore so copper fouling is out of the question.

They have solvent for removing plastic.

Copper? Tim, it sounds like you may have had some minor rust. Was it rust colored as opposed to copper colored?.

Perhaps some others can help you better than I ... but I wonder if you shouldn't have oiled it in conjunction with alcohol. When you have the barrel dry, oil it good and use the alcohol later before shooting to clean the oil out.

Bigtime, that foaming bore cleaner is a nitro powder solvent. You should really be using a black powder/substitute cleaner. Thompson Center has a product called T-17 that is a good cleaner for BP and its subs. Another word of advice, ditch the wire brush for your cleaning and use a nylon brush. Montana Extreme has a brush for just about any bore size up to .50 cal.
Let us know if these spots turn out to be rust. I doubt it with you using the gun oil after cleaning.

I used oil dumbed about 5 to 7 drops down it. Maybe not enough but i normaly use alot of oil

TC's Foaming Bore Cleaner is T17

There is such a thing as too much oil. Once the barrel is dry all you need is to run a patch lightly seasoned with oil down the bore. If you over-oil it a) it may not fire well when you load it and b) it attracts dust and grime to stick in the bore. You just want a light coating to protect from oxygen and humidity in the air.

What powder are you shooting? Your choice of solvent will depend on that. For 777 all I use is plain water. My Omega is about 6-7 years old and has a spotless bore.

A brand new rifle, shot once, with copper or plastic fouling??? Just can't have happened unless you have a burr in that barrel the size of my Aunt Ida's bunion.

What you probably see is an accumulation of oil. Oil will change colors once in a while. Take a dry patch, put some alcohol on it. Swab the barrel clean. Then a couple dry patches. Now take a clean patch, add several drops of oil, and swab the bore in short strokes, really making sure you work that oil in the bore of the rifle. Then a couple quick up and down strokes to the excess patch and pull any oil it finds and you are fine.

You have new rifles worries. When I get a new rifle, it seems I am checking that rifle over and fretting over it for a couple day terrible. All that will pass.
