What do you all recommend for a rust preventative? I always seem to get rust/brown on my patch when i run one down the barrel.
Is the rust-brown color on the patch rust, or just the color of rust. Unfortunately I've found that most of the things I've used as a bore protectant seem to turn this color over time.
I usually just use one of my patch/wad lube mixes of beeswax and some type of fat or oil, usually olive, refined coconut, or neatsfoot oil. Just enough wax to keep the fat/oil in place. Or mink oil.
But, as stated before, I swab the bore with an alcohol patch before loading my 1st shot.
I do have it from someone who gets to hunt with a muzzleloader a few times a week almost year round, that he doesn't swab the bore before loading, sometimes doesn't even clean the gun if he is going back out the next day,,,, but he only uses animal fat based lubes and animal or plant based oils. He has no rust issues or major crud issues.
