If you're reloading bulk quantities and hate individually checking each bullet for a plunk test, this is THE way to go. The only gripe is the cost, but since you only have to buy it once...

Pretty slick little device. It works well with MTM boxes and the optional tray, which I recommend as well. It will reject ammo the passes my Dillon case gauge, so it's a bit on the tight side. Fine by me!

I am very impressed by the manufacturing quality of the Hundo case gauge. I think this an absolute must for anyone who is reloading. I wish I had bought this 1000's of rounds ago!

Great product A++++

Works like it is supposed to work, and makes gauging easy!

I always scoffed at the price, because admittedly it is pretty salty. But it is worth it, if you own a progressive or make large batches of ammo you need this. It is actually slightly tighter than my barrel which I like. so even if they don't pass, they most likely would work as a practice round.

I bought one for 9mm and one for .45. The 9mm is a little too tight. The cases will fit my barrels and a Lyman Case Gauge but not all the way down on this gauge.

So there I was shooting in a match with reman ammo and had a failure to go into battery. On a Glock. Glocks are not exactly picky about what cartridges they will take. A quick tap-rack later I was continuing to shoot... until it happened again. Did I mention this was at a national event? This was the moment I decided that while I love the value of and performance of the reman ammo I've been shooting it was time to invest in a case gauge. I grabbed this on the Black Friday sale and when it (very quickly) arrived, measured over 2000 rounds. The gauge is well made and easy to use. It also makes it super easy to tell which rounds are not perfect (which I shoot in practice). Being able to measure 100 at a time is a huge time saver. Do yourself a favor - get this and don't forget the flip lid and MTM boxes - post measurement is two flips and your rounds are in the box perfectly!

This thing is a great timesaver and transfers to the mtm boxes great!

I'm a fairly new reloader (~3 months) I've been using this gauge now for about 1 month. I fill it up with 100 rounds then visually and digitally check all the rounds. Rounds that clearly don't fit in the gauge or have bad primers go in my "bad bullet bucket" that I break down and recycle the powder and the bullets. Probably about 10% of my rounds fit pretty well in the gauge, but sit up above the edge just slightly. I pick all of these rounds out and use them for range ammo. (About 90% of these rounds still work just fine at the range.) All of the "perfect" rounds go into my 100 round storage boxes that I used only for competition. Since I've been using this system I've had zero failures during competitions which sure helps alleviate a lot of my previous frustration. This gauge is expensive, but the frustration it's saved me is invaluable. I'd highly recommend it.

Just started using this. Very cool to be able to check 100 rounds at a time. But the directions mention a 'flip tray'. Why is the flip tray not mentioned with the product itself? It is not as easy to use 2 ammo boxes, the rounds don't all fall out properly. I would have purchased the tray with the chamber checker if I had known about it. I am disappointed that now I have to order and wait for something else in order to get the full benefit. The checker itself is very cool.

Was using a single case gage and would only check the first and last cartridges of my load session. With the Hundo 100 round chamber checker, I check ALL cartridges and catch non SAMI rounds. Love this tool and is a time saver.
