Guns are different. I have a few that must be cleaned every three or four shots to maintain good performance and easy loading. Do you have a special tip on your ramrod to seat your bullets? Some companies furnish or sell a tip made to fit their bullet nose. I agree, you will get more info posting this on the Muzzle loader forum.

My main Muzzle loader, a TC woods rifle, will shoot up to ten times before iot needs a good cleaning.
