sabotloader:Thanks for the report !

I intend to use a Lehigh plug/adapter in both my .45 & .50 Elites using BH209 exclusively. The Lehigh vent liner with a flash hole size of .034 should solve my cold weather ignition problems with BH209 ... I felt the Knight NFPJ flash hole was too small at .030 - .031. Also the length of flame travel looks to be much shorter in the Lehigh plug compared to the Knight NFPJ "domed" plug.. again that should help with BH209 ignition.

In your testing, what particular primer functioned (i.e. inserted and extracted) and in general was the best fit with your Lehigh plug ?

Thanks...Rob
