My process is similar to what others have said. When I am getting ready for a muzzy hunt. I run a patch down the bore to remove any oil. Then pop a couple caps & load. After loading put a piece of tape over the muzzle. I've left the gun loaded for up to 10 days & shot it when the hunt was over & never had a problem. I
always clean my muzzies the same day their fired.
Good luck on your upcoming hunts.
