While there are many effective patch lube formulas available, I think TOTW Mink Oil has attractive attributes. It’s very temperature insensitive, has a flexible consistency that allows for pre-lubed patches or strips, and with several of my rifles, enables me to shoot from 10-20 “accurate” shots without swabbing. I usually only need to rub a small amount on one side of the patch(barrel side) for good results. The cost of $7 for an 8oz tin is nice, and, it goes a long way!Reading here for some time, it does have a loyal following, never read a negative post on it.
I've found that gives me the most consistent groups.No doubt spit patches work well, but so does something like 1 Ballistol : 6 parts water.
