I can't remember if Marshall's Tech Book has it, but I stuck a bullet in the carbine today and poked it out. So, now I can say that I've slugged the bore. Question is how do I measure the slug?
I've got a nifty new digital micrometer and when I measure the barrel groove off of the flat of the slug, I consistently get .4295" (.44mag). If I turn the slug a bit to hang on the edge of the flats, it shows .4311". Which is the right measure?
