[QUOTE="Laguna Freak, post: 1934657, member: 87188"] Shooter, I’ve read through most of these posts and there is some good advice. I believe regular Hoppes 9 is so mild it takes a long (Days) soak and is still not great at copper removal. Hoppes Benchrest 9 is also mild / easy on steel but will remove copper and carbon. There are some folks here who fancy themselves the experts‘ expert and would tell you never fill and soak your bore. I disagree. I’ve seen badly copper and carbon fouled barrels that shot horrible come sparkling clean And return to sub-moa accuracy after an overnight bore fill and soak with HB9, drain, brush, and patch until patch is clean. Then lube. Hoppes Benchrest 9 states right on the label that it is safe to soak overnight. Try it if you like, or don’t. For routine cleaning, I use Sweet’s 7.62. I think its pretty good but it is harsh so I would not leave it in my bore any longer than the label says. Which is 15 minutes. [/QUOTE]
