RE: my newest cleaning method
Warm water with dish soap has been cleaning muzzleloaders for years.
Long before muzzleloaders became so popular and everyone was owning one, myself and a group would shoot rifles every weekend. We always kept a large pail of water on the stove for after the shoot (we shot back at a cabin were he hauled our water into).
After a day of shooting, we'd all sit around with our coffee cans and dish soap. Water bath the barrels, and then we'd use alcohol down the bore to dry them. The funny thing is, back then we'd bore butter the hot barrels. I don't do that anymore, but I still use a water bath to clean 90% of my rifles. Its inexpensive, does not harm the environment, easy to find as you never run out, and it works. It looks like you have a good method there Corey.
DO NOT USE THE WATER METHOD WHEN SHOOTING BLACKHORN.
