Re: Case Guage?
I've got the Lee case gauge/trimmer combo for my 30/30 rounds.
1 side has a shell holder/lock
other side has a 4 blade cutter with a threaded middle.
You thread in the case gauge length pin that fits thru the primer flash hole
and hits the shell holder/lock
If the case is within spec, it will free spin, no trimming necessary.
If the case is too long, the blades will bite in and allow trimming.
That's the Lee version that you throw in a 3/8" drill.
One of the cheaper ones I believe. Its good enough if you don't do a whole
lot of cartridges, but you may want one of the better ones if you're doing
a lot of shooting.
