The Shooters Box 45 ACP Case & Ammunition Gauge - New Patented Design ! - for Checking Your Reloads & Ammo

I own this gauge and the Dillon version. This one is much better, and works out great for reloaders. The gauge diameter is correct for real life resized brass, as opposed to gauges that are designed primarily for handloaders that use completely new components. Very versatile, and you can recheck case lengths before seating a bullet into the brass. Then use it to check the cartridge OAL. I plan to get the rest of the ones they make in different calibers.

This is easily one of the best case & ammunition gauge I've ever used for reloading .45 ACP for my 1911's. It has helped me to troubleshoot issues I've had with a few case/bullet/seating/crimping combinations in a matter of minutes were other tools failed to give me accurate information. I will be buying the other calibers for sure!

This case gauge does more than just emulate a chamber. It measures minimum and maximum case length. Using this helped me see that I was crimping my cartridges a bit too much and also had not belled the case mouths enough! I'm SOLD!

These are great. Every time I start reloading a new caliber I put a reloaded shell in the gauge to be sure my sizing is correct. About every 50 rounds I drop another in the gauge. Has worked extremely well for me solar. I do a lot of handgun reloading.

Cases that fit RCBS and Dillon case gages would no fit this gage even after taper criping ammobelow specs

It's from the Shooters Box.... You can't go wrong! Highly recommended.

This is a very well made case gauge that will tell you if your rounds are within SAMI spec, and it's made in the USA !

This gauge works for both loaded and resized brass. A must have for reloaders with target pistols.
