Hey thank you. I have some to use from my gun stock finishing. I honestly have never tried to clean one this bad, it just won't come out after hours of trying brushing and soaking patches. Just keeps coming out real green. And still looks horrible with a lot of raised spots in both lands and grooves. It really doesn't look so pitted, just really really fouled. I was about to try plugging the breach end and fill it up to the bore with benchrest Hoppes and let it sit over night. It'll get better, it's gotta before the fall so it can hit the woods! Thank you.
