Pella hunter
I swab after every shot at the range, that way the bore will be about the same as when I shoot in the field hunting. If I were hunting and needed to make a quick second shot, and in the timber I hunt you very seldom will ever get a second shot, but if I need a quick second shot no swab just reload...
I am a plain "keep it simple stupid" type guy so I just use reuglar windex. At the range I have patches already made up and stored in a (no laughing) a Tuck jar - one of the short ones. They can stay in that container for months and still be just right. The key to patching between shots is not to have a wet patch! You need just a damp patch the dryer it is, but moist enough to collect fouling, the better. When you patch make sure you patch with short quick stokes until you get to the bottom...
Hunting, I just use, another KISS principle, a spit patch. Lay the patch on your tongue and get it moist - doesn't take much...
good luck... I recommend patching, especially if you are shooting sabots...
