Correct me if I am wrong, but it is speculated by many that the 777 crud ring is caused not exactly by the powder but the 209 primer pushing the pellets and projectile slightly off before full ignition which created an air gap where pressure and heat shoot up? Where Loose powder won't have this problem near as severe?

Thats the reason I didn't have any problem with my new power stem from knight and loose 777. So I figure.
