Copper fouling

[HV-Muzzleloaders]

Thanks for your post & the info. I learned something new from it too.
I'm makin some Bills or Bens liquid spray on lube that dries to the touch but leaves a micro film of lube on your bullets. I'm testing this ( its new to me too ) on cast conicals in my .50. I'll get to testing out some jacketed bullets with it too, to see if theres any fouling or cleaning differences. Perhaps polishing his bore & using a spray on lube like this will completely alleviate his fouling issues. Its food for thought.

I have mixed HBN with synthetic wheel bearing grease from AutoZone to use as a rifle lube. I put it on the cam pin and locking lugs of AR-15s.

You might try adding a little HBN to your formula.
