While no expert.. when I apply the anti sieze breech plug grease, I put a nice thick coat on the threads of only the breech plug. I fill all the threads so you can not see them. When I screw the breech plug into the breech of the muzzleloader, I do get an overflow of anti siezeinto the outside of the breech. I simply take and wipe this off with a Q-tip before heading to the range.

Then before I start my shoot session I pop two 209 primers (or #11 caps in the case of the Wolverine II) and this will blow any excess lube away from the breech plug and the fire channel. To double check that I have a good clear fire channel, I put a clean white patch on the loading jag and push that to the bottom of the breech through the bore. I then pop a 209 cap and pull the patch back out the barrel. If you have a clear fire channel, the white patch will be burned from the 209 primer having gone off. That means you have a good fire channel and the patch will also draw any excess lube, oil, or anything else, back out the bore.

Now you have a clean dry barrel, with no oil or grease in it, and a clear fire channel. So go ahead and load as normal.
