Well, a few more tidbits?
Took a look at a couple of fresh out of the mould 225438's of the Lyman persuasion and find the approximate diameter of the gas check shank with Lyman #2 alloy is ~ .215". So close, yet so far. Dang it....
Waiting for a call back from a custom brass maker to see if they want a piece of this with their fancy CNC equipment. If they are game I will start the ball rolling just to see how it works. It's only money.....
What are we going to name this thing?
