In my inline rifles that shoot a 209 primer I make a swab solution 50/50 out of isopropyl alcohol 91% and car windshield washer fluid. Dampen not soak your patch. Then with a cleaning jag, start working that patch down the barrel in 3-4 inch spurts, getting deeper into the barrel as you go. When you get to the bottom you might feel a crud ring, just work the patch good over that area and it will disappear. Then bring the patch back out of the barrel, again with short strokes. This help to keep the patch from getting stuck. After the wet patch then run two dry patches through the barrel to make sure the bore is nice and dry. I do this after every shot if working up a load.

In a traditional rifle I do the same routine except I use just isopropyl alcohol without the wind shield washer fluid mixed in. This help to stop hang fires and misfires from swabbing with the wrong mix.

Some rifles I do not need to swab at all. It all depends on the projectile and powder I am shooting.
