+1 to what sabotloader said about using the Knight breech plug tool to install the Lehigh plugs...or even the Knight NFPJ plug.
I had to drill out the center of the Knight tool to install the Knight NFPJ plug as well. My guess is the breech plug tool was manufactured before the NFPJ came out... and the NFPJ and Lehigh plugs have a longer neck than the FPJ plugs.
Very easy to drill out..... think I used a 5/16" bit. Drill until the tool gets a full purchase on the lugs.
