I watched a buddy of mine spend 2 hrs trying to clean the T7 crud ring out of his encore last fall at our cabin. He shot 3 times without swabbing.... the crud ring was so pronounced it took him over an hour to get the first patch back up past the ring. It kept pulling them off his jag, and he'd have to put a patch puller on and retrieve the torn up patch.

It was comical actually. He was using 3 T7 pellets. I looked at his rifle after, it was obviously not pristine in the bore...which I'm sure made things worse. Knowing him, he's not one to be in a real hurry to clean his rifle.

Pyrodex doesn't really develop a bad crud ring like T7, with #11 or 209's. I still swab between shots, except when in the field.
