Hundo 100 Round Case Gauge for 9mm Luger by Shockbottle

If you are a serious shooter, you are probably a serious reloader. If you are serious about reloading, then you probably own a case gauge. If you have done enough case gauging, then you know that case gauging sucks.

If you understand how lame gauging ammo is, then this is the product for you. You will spend an absolute minimum time gauging your ammo and a maximum time doing whatever else you have on your plate. Quite simply, this is the highest capacity case gauge that you can buy. Your friends will be jealous, your wife will have renewed interest in you, and your children will start to show you respect. Well... maybe all that stuff wont happen, but you wont care because you can gauge ammo like a boss.

100 dollars may seem stout for a simple device like this, but if you compare the price of this to other gauges on the market, you will see that this is actually the best deal out there. Nobody else even comes close to the value offered by this unit.

The 100 Round Chamber Gauge is ideal for shooters who want to ensure better reliability of their ammo in chambering and extracting. The Chamber Gauge is machined from aircraft grade aluminum. This Chamber Gauge is specifically designed to utilize a 100 round ammunition box as a "flip-tray", then can be flipped into an ammo box bullet down and ready for the range.

    No SAAMI spec for COL

    Posted by David on Apr 21st 2021

    While a huge time saver, this gauge is not useful for gauging overall length. The depth of the gauge is a mere 1.044". I know some 9mm reloaders seat bullets longer than SAAMI, but I and many others don't. Aside from that single caveat, the build quality is excellent and it's likely to be compatible with any 100 round ammo cases you already have.

    Excellent quality gauge.

    The gauge is very well made and has sped up my case verification. I would like to get other calibers in the near future.

    Fits 356 coated bullets

    Was a little worried from reading different forums that the oversized coated bullets wouldn't fit but my .356 blues, black bullets and SNS all gauge properly.

    Let's face it - this is not cheap, but it's well machined and easy to use - really speeds things up. Recommended.

    Great Case Gauge

    Posted by Steve Champine on Aug 5th 2020

    Works great when used with the flip tray and the 100 round box. Quickly gauge, count and load 100 rounds into a box for matches.

    Excellent Double Check!

    Posted by Tim Downing on Aug 4th 2020

    I was pushing the limits on speed for reloading and needed something to check my work. A case gauge is great but one at a time defeats the purpose of speed. With this 100 count case gauge I can flip the rounds into reload containers after checking them and save a ton of time, plus achieve my primary goal of checking the reloads viability.

    Awesome for Chamber Checking in Bulk

    Posted by Dave W on Jun 4th 2020

    This Chamber Checker works great. Allows me to produce a large number of rounds and then check them all at once. It has definetly improved my production time. The quality is great, and if it seats all the way I am golden. If it sticks up a bit, I know I can check it in the particular weapon it is for and see if there are issues. A bit help to my production activities.

    Very impressed, cant go wrong with this , and if you get the boxes makes counting and checking much faster ... I was surprised on how heavy and well made this is ... just buy one already!

    This is a very nice bit of kit, and really essential if you are competing. We all know that 1 fat round WILL show up at the worst moment in a match, and this is the fastest way to screen that out. The gauge does run tight - I cross checked it to my guns to find out just how off my guns will tolerate, and now I can weed those out quickly to the "practuce" box. I am much more confident that when stuff goes sideways at a match, it will NOT be due to a round not chambering

    This is awesome!

    This is the perfect piece of equipment I needed to help speed up my reloading process. I can drop in a 100 9mm and see if there are any resizing issues. I wish I had this earlier in my reloading endeavor. Now I wish you would make one for 308. I definitely recommend this product.
