i'm just a hunter. for a new rifle i run a patch thru the barrel soaked with hoppes 9. then a few clean/dry patches. then i shoot enough to get scope dialed in. no more cleaning until after hunting season. post season i run a soaked patch, followed by brass brush, then dry patches until last one comes out clean. last patch thru the barrel is soaked with oil. i've been doing this since 71'. as always, ymmv.
