Since I've been experimenting and getting re-acquainted with my T/C .50-cal. Renegade for about 4 months now at an outdoor range, I had been wiping my barrel between patched roundball target shots using Goex ff, mostly with bore butter. However, after reading a lot of posts here, I decided to try my own experimentation for an after-every-shot bore swab. My last range session I used an equal mixture of 70% Isopropyl alcohol, Murphy's Soap Oil and Castor oil. It's a fairly thick and gooey mixture, and it seems to have worked quite well, because my last grouping at 50 yards using .490 Hornady round balls and .018 ticking patches lubed in TOW mink oil was the best I've had. Four balls in the center within one inch of each other. It might have been five but I dry-balled the fifth and left the range early to pull it (that's on another post, with mixed pulling results). Anyway, I poured my concoction into a small glass Civil War-era pill bottle with a cork stopper, and the mixture was fairly thick and mixed well and soaked into pre-cut patches I kept in an old Sucrets tin. I'll probably experiment some more, using a bit more alcohol, but I was impressed with my results on the very first go-round. Anyone else use a mixture of alcohol-Murphy's-castor oil before, or a variation of it? I'm curious. I'm sure there are hundreds of different successful concoctions out in BP land you have used. op:
