Very tight tolerances. Much tighter than another brand ammo gauge that I own.
Getting this gauge actually got me to buy a new seater die to get all of my 9mm loads to fit. If your 9mm loads fit this gauge, there is no doubt in my mind they will chamber. Highly recommended. Now if they can figure...

Awesome Product. Have purchased 2. In comparison to the Lyman 100 Rounds Case Gauge, the DAA is a far better product, from tolerances to ease of use. Highly Recommended.

Checking your finished rounds couldn't be any easier & faster. I love the included flip tray. After inspection the flip tray helps get them in MTM or Dillon 100rds boxes. While it was designed more for the Dillon ammo box, it also works well in the MTM with a little jigging. One benefit I didn't...

Serious shooters understand the importance of testing their ammo before a competition. After all, most malfunctions in semi-auto pistols can be traced back to out-of-spec ammo. Unless the ammo is perfect, you can’t really expect a trouble-free match.

The Double Alpha 100-Pocket 9mm Gauges are precisely machined from Aircraft-grade aluminum, then tumbled and anodized for a striking long lasting finish. These large gauges include a Delrin flip-tray lid, which makes it quick and easy to transfer the tested bullets from the gauge and into your Dillon Precision Ammo box.

That’s right, our 100-Pocket Gauge is design smaller and tighter, to match exactly the dimension of the compact Dillon ammo boxes, which are preferred and used by so many shooters worldwide.

The compact size and tight pocket layout of our Gauge holes also make it easier to drop in multiple rounds from your handful of ammo, thus filling the holes faster and easier than other gauges which have their holes more spread out.

Another cool feature of this gauge is that while the overall height is tall enough too allow the bullet to enter all way the into the gauges while it is laying flat on a table top (30.1mm tall), the underside of the gauge has a cut-out pocket to enable you to push up on the bullet tip of a round that may be tight and stuck in the  pocket. You won’t have to go look for a plunger tool to use, as you may with other gauges. Simply push up on the round with your finger until it pops loose.

Using the DAA 100-Pocket 9mm Gauge, you will be able to test you ammo, and place it into your Dillon 100 round ammo boxes faster and easier than ever before.

Product includes:

1x Aluminum 100-pocket gauge block

1x Delrin 100-hole flip tray.


Available in Black only.
