I've some questions about a Mosin 91/30, it's nothing special just a '42 standard refurbed Izhevk with a counterbore. Picked it up about six months ago at a show and have been trying to get to hit paper at 50 yds with either J words bullets or a light weight 100 grain cast plinker.
Here's my problem, I've scrubbed the bore with a good bronze brush and plenty of Hoppe's #9 till the patches came out clean but after my last trip to the range I wet patched the bore with Hoppe's and forgot to dry patch it. Well when I finally used a dry patch it came out really green. Looks like there is a lot of copper fouling in the bore. Been wet patching and then dry patching after 8 hours or so all week and still am getting a lot of copper fouling out each time.
A buddy told me that the copper fouling isn't that big a deal, all it does is fill in the rough spots in the bore. I think the rifle will shoot better when the fouling is cleaned out. Who's right?
I have no problem working on the bore till clean, it might take a few hundred patches, a few brushes and a couple of months. It's just is I would hate to spend all that time working on the bore and end up with something that shoots worst and have to hear about it from my shooting buddy for the rest of my life.
Also any tips on how to get the copper out beside scrubbing and patching?
Thanks
