I went to the range yesterday and made some changes to my procedure. I fire a round. Let it cool. Swab it out with two different alcohol soaked patches. Blow out the nipple. Swab with two dry patches. This doesn't get it all out, but it does get over 90% out. I then wait a couple of minutes and load another round. Fire. Repeat. This is a combo of several of your procedures. I also removed the plastic cap of the powder belt bullets and added some bore butter. They were really stuck on. I found them on the ground near 25 yards. All my bullets hit an orange size target at 100 yards and that is good for me. Thanks for the help. Now I feel confident and can go hunting.
