Yeah. The flint was 1/2" x 1/2". It really wants a flint 7/8" wide x 1" long.

Regarding my perception of ignition speed with the Pedersoli lock vs. my Lyman locks. The Lyman's seem to be instantaneous - like a caplock. My impression was the Pedersoli was not quite as fast as either of my Great Plains rifles.

Well, I got to thinking about that last night and realized that I have RMC touch hole liners in my GPs. Those liners are coned on the inside and have a hex socket on the outside for an Allen wrench, both of which act to place the main charge very close to the pan flame. The Pedersoli has the factory flat faced liner with a screwdriver slot. That may be the difference. If I end up keeping this gun it will get an RMC liner.
