A lot of it will depend on how you treat your rifle. Start with a clean dry oil free bore. Then a small amount of powder is what I use to fowl the CVA Staghorn I shoot. A quick alcohol swab through the barrel and then load as normal.
If your having troubles getting the powerbelt to seat, then I suggest you check you powder charge amounts. You might also want to go to a musket cap instead of the 209 ignition.
If swabbing is a concern while hunting, I always carry a small plastic bottle with 20 or so alcohol saturated patches and a clean jag in there, in my fanny pack for my rifles. I do this more for the even that I should fall and plug the barrel and need to field clean the rifle. I can also swab that way if the loading should ever become hard. So far I have never had to use the little bottle of swabs... but I know they are there....
