So its basically safe to say, They all need some reworking at the factory.

The Wolf i have " actually my bro in laws" has VERY little primer blow by and fired blackhorn with W209 and cci 209m's greatly. My nephews wolf on the other hand is a good deal dirtier and his needed the .035" flash hole. I think primer fit plays an important role in weather BH209 is going to light off or not.
