I use a Brass Brush (just a couple of strokes) just down and out to loosen the fouling then swab it clean.
I also shoot with a Fouled Bore, it shoots where I want it to hit and I know it will. Every few Days during the Season If I havent got a Deer yet during Mid Day I will shoot it, give it a quick Clean (to be sure Im not leaving the fouling in the Bore too long) then shoot it again to refoul it, check it, and Im ready again.
But I also noticed My SS Barrel can take Fouling in it longer without harming it compared to a regular Steel Barrel, plus the SS Barrel cleans up so much more easily than a Steel Barrel so Brass Brushing is kept to a Minimum. I have a Nylon Brush to try out and Im gonna see if it works.
