Marshall has it right on the money. Clean your barrel, then clean it again. I in the past, I would drive a rubber cork in the muzzle and fill the barrel with Shooter's Choice and leave it over night, to remove copper fouling. Then it dawned on me that there was nothing that a jacketed bullet could do, in a 45-70, that a cast bullet could not do. I have 300 Remington, Speer 405 jacketed slugs in the loading room that I bought in the 70s and have no reason to use.
Once I stopped shooting jacketed slugs, my accuracy has remained constant. There's just no reason to shoot the jacketed stuff.
