Re: barrel cleaning methods
I run a bore-snake through my bore before each range session with my 308s. This seems to get rid of any leftover powder fuzz, and it puts my in the habit of ENSURING THE BORE IS CLEAR, every time I am about to use my rifles.
I will use some Hoppes #9 occassionally, when I think of it, to clean my chamber. I fire about 200 rounds/month or so (spring/summer/fall), and we're talking a chamber cleaning once a month. Every couple months when I feel like it, I will run a wet patch of Hoppes 9, let sit for 10 minutes or so, run two dry patches through, then I fill the bore with GunSlick Foaming Bore Cleaner, tip the rifle so the barrel is slightly muzzle-down, and wait a couple hours. Two or three patches (using a bore guide OF COURSE), and the bore is squeaky clean.
My opinion is that GunSlick Foam does a fantastic job on Copper, but not so much on powder residue. That is why I use the Hoppes 9 first for the powder, then the Gunslick for the copper.
