Watch gunblue490's* two videos, Gun Cleaning and Solvents; How to Clean Your Rifle Professionally... then evaluate for yourself his claims. I found his assertions to be true at least with regards to my rifles a year or so into following his basic principles. The only difference being is that I'm using C4 because of it's superior carbon removal capability.Need to amend my prior post, I started with C4, then proceded to Cu+2 and bronze brush for the copper. In this instance, I wanted all the copper out fully aware I would need to re-season the bore in the future.
This particual 7RM was my primary hunting rifle in the 80s and early 90s and hasn't been fired since my last elk hunt in 1997. I'd periocially pull it out and run a couple patches through re-oil and put away.
Last week I borescoped it with my Teslong, and was stunned at the amount of copper in the bore, every groove was lined from the leade to muzzle. Wish I'd had the presence of mind to take some bore pics before I scrubbed the copper out.
Shooter's Choice was my previous solvent of choice and had also used Butch's Bore Shine. Like you, I also clean in the house and although the odor never bothered me, my wife wasn't particularly happy about it.
I absolutely believe there's a point of equilibium, especially with factory barrels (probably more so with Savage), and let the target tell me when it's time for a deep clean and re-season. Since this particular rifle is now more or less a safe queen I'm fine with it devoid of copper. ;-)
Based on the research I did, there are similar posts by others that address the same issue of achieving copper equilibrium to promote consistent point of impact.
