So I just pulled some of my nice clean Lake City Match brass out of the tumbler after fire forming them to my new Savage rifle. I got out my trusty Lyman case gauge and dropped a few in just for grins. The cases drop in all the way but maybe an 1/8 of an inch. Most will even go nearly all the way with a little finger pressure! These cases have not been sized in any way. My last .308 rifle would leave pretty much the whole neck length outside the gauge which makes sense. I neck size for the most part and that is all the cases usaully need. Is this just a sign that the chamber was cut with a tighter neck diameter? I checked standard reamer prints, they call for a .3435 neck. A match chamber would be .3415. My brass is measuring .344 after firing. This is a Shilen chambered barrel. Anybody else run into this situation?
