Please try mixing your own lube, like the recipes that work so well for me. The bore butter lube, although seeminly gret on slugs, seems to be very poor with patches. The guys on the other site I frequent speak of a residue that coats and fouls the bore.
; The easiest and cheapest to make is Murphy's OIl Soap mixed with Neestfoot oil(not compound), 50:50 mix, shake it up and squirt it onto a pile of patches, and use your fingers to work it in. It's slippery for sure, but sure works nicely in our rifles. It's probalby good for the hands, too - HA! Sure cleans off the grime.
: I use throat-losenge tins for patch containers, as well as a brass flint and steel container with hindged lid from www.trackofthewolf.com
