You describe using a spit patch. There is nothing wrong with it, and lots of things that are right! For one, it does not use petroleum products. Two, you never run out of spit. On a range, where you expect to fire the round within a few minutes, spit can keep the fouling soft, lubricate the barrel, and help the patch seal gases behind it. Use a spit patch in combination with a card, or fiber, or felt wad, and you should get very good accuracy. The only thing better would be to run a lubricated patch down the barrel when or after you seat the PRB. The chronograph shows this increases velocity, and also reduces the standard deviation of velocity for a given load. That lube in the barrel will keep the barrel one shot clean, regardless of the temperature and humidity where you are shooting. You can use several different lubes to lubricate your patching materials, including using water soluable oil and let the lube dry, so that you are putting a dry, lubed patch down the barrel. That would be the alternative to using spit. For informal shooting, where pinpoint accuracy is not expected, stick with spit. However, if you are going to shoot against someone for money , or other prize, then by all means use the lubricated patching. Spend some time at the bench shooting these various combinations, so you know where the Point of Impact is for the different combinations. Take notes, and keep them handy as a reference. I had a nicee .45 rifle that would shoot as well as any gun out to 50 yds, but wasn't worth much beyond that. I shot spit patches out to 50 yds, but when I switched to lubricated patching, groups tightened up for me, and I was lucky that they shot to the same POA at 100 yds. It doesn't work that way with all guns.
