Definitely nothing new, but maybe an alternative for guys like me with Okie skills.
This one measures total allowable case length - bolt-face to end of neck. The brass ring is glued on a bullet shank. Bullet is a stiff slip-fit in the case neck. Drop it in the chamber and close bolt. Primer pocket is drilled out to accept a 1/4" shaft to re-expand the gauge.
I check three or four times, and pick the shortest measurement as absolute longest. Then subtract.005" as my max case length. It is usually at least10 and sometimes 20 thousandths over what chamber specs show. Using this I created my "grow to" length and decide just how short I wanna trim.
This one is for "touch lands" measurement. Simply a split neck to provide a slip fit for whatever bullet you're using. Same deal - chamber and close bolt a few times to get an average measurement. I call it touch, because it isn't tight enough to even be a light jam.
I keep a set of these in each die box with the stats for the particular rifle I'm using.
I know there are commercial versions of this, and I've got some, but this works pretty well for me.
Advice or criticism is welcome -- I think.
