Re: Bore cleaning agent ? CR10, butches, shooters choi
I like the Outer's Foaming Bore Cleaner.
Instructions say to allow it to stay for 15-30 minutes. I tend to consider this a minimum, and sometimes let it work for as long as overnight. Don't let it dry out.
Patching is all that's needed.
My .260 match rifle shoots about 50rd per session, and the patches tend to come out clean after a second soaking.
Getting OCD and doing a third soak gets the bore clean enough that a borescope cannot find ANY fouling. More than two soaks is overkill, and the bore needs a light, even coat of oil after final patching.
Simplest method and most effective method I've found so far.
My L-W barrel has about 1500rd down the bore and has seen the brush only once, to see if it made a difference. It didn't.
