You also have to be more careful swabbing the bore with the GPR patent breech since it doesn't clean out particularly well when using a full width jag and patch. I use a regular rifle cleaning rod with a slotted patch holder to clean that portion out. Otherwise rammed down fouling and excess cleaning patch lube/solvent builds up in there and can cause ignition problems. It's handy for keep you from ramming a ball down to the breech w/o powder, but other than that, it's a hassle for cleaning with a normal BP rifle kit.
