roadkill7205, I still have a bottle of Hoppe's No.9 Benchrest I bought ages ago, because I just don't use it anymore; I stopped using it the day I discovered Barnes CR10. I've never tried Butch's Bore Shine, so I can't really comment on it, but I've read it's supposed to be good.
I just used CR10 and house cleaning ammonia on mine until the patches came out clean, which took quite a long time. I then cleaned the bore with J-B Bore Cleaner and polished with J-B Bore Shine. I have no idea if that will make any difference, but it has on other guns I've tried it on.
Oh, and I don't really need mine to be a tack driver, I've been shooting my deers from a stand at 50M for years now, and that is not about to change. But this is a very nice rifle and I think it can do better than it's actually doing right now. I mean, if I can get it to shoot 1.5" groups at 100M with any degree of consistency, I'll be quite happy. I use my .300 Wby for longer distances, and that one can give me 1/2" groups at 100M, if I do my part. So I don't really need this .308 to shoot that good.
By the way, I took the barrel and action off the stock and discovered that half of the rear bedding surface was missing. It looks like the epoxy cracked and lost the left side, but they just let it go like that. Maybe that was causing the wandering shots. Anyways, I put some extra JB Weld in and have it curing in the basement at this moment. We'll see what it will do this weekend.
