Barrel down is the ticket. I have noticeably better ignition results at matches. For cleaning I just do dawn and water, WD-40 to displace the water, then Rem Oil for my final lube. I just haven't had the best results using ballistol, plus the vapors make me cough. There's a 100 ways to clean a muzzleloader, we all find what works best for each of us.I buy mine from sutlers at the N-SSA Nationals in Winchester VA. I use it 50/50, cut with water. The smell doesn't bother me at all. It only takes me a few wet patches to clean my muzzleloaders. I then run a patch with Bore Butter down the barrel and wipe down the exterior metal with BB. I store my MLs barrel down in the safe.
Haven't had any problem with my flinter. No rust either
