I dipped every time . I recently did an old 38-55 lever Winchester, with dark bore, from the muzzle.Stuffed the action with paper towels.I cleaned the barrel with several a different solvents and brush and used JB bore paste.When the patches came out clean or darn close , I degreased and applied the DT with a mop. Let it set overnight muzzle down and then fired about a dozen rounds thru it..
I cleaned it again for about 45 minutes and took it to the range again after a few days
Another 30 rounds and I wasn't getting any key holeing which I expect was from really excessive lead fouling.
However it did take me another 30minutes to clean and I gave up when patches were still showing some signs .
Email to Muledeer and he said it should get better.
Time will tell and I need to get some bigger diameter cast bullets.
