Really grateful for all the comments, just working through it all

I'm guessing that 'Aqueous cream' would do as well as E45 (both seem to be basically Liquid Paraffin, White Soft Paraffin) - though a guy I occasionally see at the club uses a home brew that adds beeswax to that (I must try to get the 'recipe' sometime

So.... if I was to use a wad (lubed or not), would that allow me to skip the filler??

....btw, when I take my Taurus .22 LBR out, I just shoot it ....I can see that a cap 'n ball revolver is going to be a whole world of fun
