Cleaning, and the modern MLer over engineering something really simple.
Several rules about black powder:
NEVER ever get petrolium based oils around your rifle. NEVER
The chemically react with burnt black powder and make sludge.
Those that do, guess what have to wipe after each shot.
ANYTHING you use in your modern firarms, keep the hell away from your bore stuffer.
If you cant get the handle of using hot water, and a wee bit of dish washing soap. Then by all means go buy some Thompson Center ML bore cleaner.
The cool thing aobut hot water is it heats the barrel, and then dries it out really fast.
LUBE: Use only T/C Bore Butter, or one of the many knock off brands. all natural, NO OIL.
I shoot 20-30 shots at a time, 1-2 times a month. I clean my rifle after every shoot, Ive had guys break thier rifles, and use mine, so we double shot it, 40-60 times and still not a wipe needed.
