All strong copper solvents say they need to be removed from a barrel in about ten minutes. My question is how do you make sure you get it all out?

Run a pile of patches through it. Then run oil patches, then dry patch. at least thats what i do.

i usually run a solvent soaked patch down it till it comes out clean then i run dry patched down it till the come out dry the i oil it then run it till dry it again

I just switched to Gunslick foaming bore cleaner. Problem solved.

yep, dont use the harsh chemicals...use the foaming cleaners...forget who makes mine, but it doesnt even have a smell to it..fill the bore with foam, let soak for a half hour, patch it dry and your bore is spotless. only thing i found that would get the copper out of the 22-250. i dont know if its the velocity or the bore still being new, but that thing coppers up pretty quick and pretty bad. never had a rifle that collected so much copper...solvents of all kinds got laughed at...i tried a couple...love the foam though..

After I use Barnes CR-10, I run some Shooters Choice through the barrel with a nylon brush, and then a saturated cloth patch with Shooters Choice. Next a dry patch. Good luck.

Run a few dry patches thru the bore and then run a few oily patches thru the bore and chamber pointing the muzzle downward. In the future buy a can of wipeout foam...it doesn't get any better. I am done with the brushing and harsh chemicals. If you happen to have a gun with a great bore like a Sako,Tikka or a custom rifle it is even easier..4-5 patches and your done and you don't even have to oil the gun unless it is to be stored for the winter. Good Luck

When using sweets or CR-10 or butches, I might take some brake cleaner and put on a patch, it will remove any ammonia based products. But so will heavy oil use.
