I do the same thing with PRB, shoot all day without swabbing. But then again, the patch around the ball is swabbing every time I load so maybe I am swabbing every shot.

Not every gun gets a crud ring. I have one inline that has never had a problem with the 777, or any other powder, crud ring. Both of my kids inlines have issues with it no matter what primer I use and one of them has issues with it with more than just 777. One of my sidelocks also has CR issues even using #11 caps with 777. Now that I said that, I guess the powder may also be a contributing factor along with the gun design. In fact I'm sure there are multiple contributing factors as have been postulated in the above posts.

I guess we are all right.
