Daryl-

Thanks for the word.
I'll give that stuff a try, not likely before my hunt in siskyiou in a couple of weeks though.

I went ahead and tried out the 50/50 castor and murphy's patch lube these past few days.

Tried that out with .020 denim in a .50cal caplock rifle my dad had built before he died (I had to do a lot of work to it, including fixing the gouges on the rifling lands, followed up with a lapping job--the maker really screwed the pooch on that one) and got it shooting into an inch at fifty yards from a standing position.

This castor/murphy stuff seems to work pretty well, the fouling is just about soft enough to get a second shot loaded without having to run a cleaning patch down the bore between shots.
Is the Leigh Valley lube even better?
