Me? Obsessive?

300 rounds of .40 S&W after I ran them through the case gauge:


I’m probably not quite as obsessive as you might think from the layout of the rounds on my desk.

I use a case gauge that holds 20 rounds:


This speeds up the gauge testing and allows me to count the rounds easily by organizing them into groups of 20 before I put them loose into an ammo can.

  1. Well, that’s certainly faster than a single cartridge gauge, or using the actual barrel or cylinder from the gun.

    But it isn’t as fast as incorporating that feature into a reloading press, or a separate press-like machine to orient and drop the loaded cartridges into a test gauge.

    500 rounds/hour is a very comfortable pace with a Dillon 550, which is 8.3 rounds/minute, or about 7.2 seconds per round. I’d be more than willing to accept a slightly lowered production rate if the press incorporated a drop bullet gauge. I’d suggest adding a cartridge gauge to a 5th die position (IIRC, the 650 and 1050 are 5-die), but pushing a cartridge up into a gauge wouldn’t work.

    Saw a piece last week RE: a tailor in England using multiple scanning lasers in a booth to get precise body measurements for cutting a suit exactly, eliminating the necessity for fitting adjustments after the suit is made. I suspect the same techinque might be achievable with a reloading press.

    Mike Dillon, call your office (also, whomever at Hornady and RCBS runs the R&D department).

    • I have a Factory Crimp die which comes very close. In several thousand reloads, from my own fired brass, I did not find a single reject. When reloaded once fired brass from other guns I get about one reject for every 250 rounds (from about a 3000 round sample). But that reject, while sticky in the chamber of my gun, works fine. I’m considering dropping the case gauge check.

      If I run the brass through a Redding G-RX Carbide Push Thru Base Sizing Die then I have no rejects (out of a many thousands sample size). But that involves setting up the press for the resizing and then setting it back up for reloading as well as the resizing operation.

      • I had completely forgotten about the push through sizing die. If I can remember where I stored it, I’ll put my Rockchucker back into service with one.


  2. Not a reloader here: When you have the 20 rounds in the holder, can you tell by sight or by feel which ones have the bullet seated too deep or too loosely?

    • No definitive test for too deep. But over length is easy with my Midway and L.E. Wilson case gauges. The Double Alpha gauge doesn’t give me a strong clue. But I have never had any issues with the seating depth once I had my seating die set up. Those type failures just don’t happen. It’s the brass with bulges which is the big issue with pistol rounds.

  3. I bought a case gauge a while ago after running into factory ammo that was out of spec. Blazer Brass, if I remember right (9 mm). A substantial percentage of that box was slightly oversize, or possibly overlong.
