Yep, can be true. Just cause one guy had one experience on one gun, doesn't mean much.
But they are designing the hole to control this I have noticed. I know the revolution changed its breach from when it came out due to this. so for some guns designed to keep the spark down, you might be hurting yourself.
I have only experienced crud rings on T/C's, never my knight. The believe which seems pretty valid is that in some guns, the initial impact of the 209 pushes the load up before igniting causing an air gap.
Actually 4 guns total. I just didn't mention the 3 guns I used #11, Musket cap, or 209 primers in. Of course that was back before all this primernonsense started. Only difference I noted then was a slight POI shift.
