Since using BAC and CR plus combinations of the two lubes, I have fired 390+ CB's in my Marlin XLR 45-70. From 285gn- 525gn boolits, checked and plain base, velocities from 700fps to 2180fps. Boolits sized to .459"-.460", paper patched .452" boolits to .460". All with smokeless powders.
The only cleaning I have needed is with a patch in Butch's Bore Shine, no brushes, steel wool or penetrating oil required. My bore literally gleams when I use a bore light to inspect.
Honestly, at the price and the quality offered, I don't bother making up some 'witches brew.' The only other lube I would like to try is Recluse's, unfortuantly no JPW available in Australia.
