I use SPG on my minies these days but have a buddy in Atlanta that I cast for and he shoots his musket rarely and need to find a lube for him that will age well. I have lots of old minies on which the lube in dried out and crumbly. Have shot some and they may just as well not be lubed at all. Don't remember what I was using in the old days. Being an NSSA member my SPG lubed minies don't sit around long enough to get the age test. Jaeger
