Tumble in the dryer makes it softer. For lube don't overlook plain ol spit. Pop the end of your patch strip in your mouth, get it good an wet, seat the ball and cut the patch off flush with the muzzle. It's not a hunting lube where the same load may be left in the gun for days or weeks but for range work nothing beats spit patch. This is especially true if you don't enjoy swabbing the bore after every shot. Spit makes that unnecessary, I've loaded and fired 30 rounds in an afternoon and when I clean my gun for the night it might just be cleaned with spit as well. I think much of the fouling which build up in the bore is residue of the patch lube, spit patch shoots very clean. I favor tight loads for accuracy. In my .45 I shoot a .451" ball with .017" pillow ticking and that takes a good lube to load, spit does fine. Spit is free, doesn't leave a greasy mess on your hands, your clothing and in you possibles bag, and you never forget to take it along.
