What i refer to when talking 'crud ring' is the crusted ring near that froms all the way around the barrel near the point where the projectile sits on top of the powder load. I have not shot a lot of any of the Pyros, just enought to know I am not fond of it, but I never experianced a 'crug ring' with Pyro - just a lot of 'crud' up and down the barrel
