Bronko, you will find you get far less carbon build up in the flash channel if you have a good primer seal AND avoid mag primers. I can shoot my Knights and my NULA all day and never need to clean the flash channel. Over 95% of my shots have been with a plain old Win209 and nearly 100% with a standard CCI in the NULA.

Never had a single hang fire, delay or fail to fire ever even after 40 shots. I don't even bother cleaning my NULA plug after a range session. There is almost no carbon in it when i do.

Better internal geometry helps a great deal too and a 1/8 flash channel is not quite ideal. 5/32 has shown to work better in my plugs. All three from different manufacturers. The Savage plug was one of the plugs used to develop BH209 and you guessed it....its a 5/32 flash channel. My Lehighs and NULA are also 5/32.
