EGW Ammo Chamber Checker .223 7-Hole

Works as advertised. Even if the case rim is sticking out a little the case will still chamber and hand extract smoothly. If you’re a reloader (why else you buying this?) and cycle through the same brass over and over to the ? amount of times fired this will not catch split necks. Either have to catch it on the press or still hand/eye inspect each batch.

Fit perfectly

Great product well made and works as it should Highly recommend!

Had several hundred reloads I needed to check for size. Some neck-sized only, some full-length sized. This made sorting that ammo a breeze. Now it will get used for checking ammo I intend to use in my matches. Bought one for 9mm too. While it would be nice to do 20+ rounds at a time, this still gets the job done and really helps instill confidence that the rounds will chamber easily.

Gage checks shell headspace. If the shell sticks out, the shell needs re-sizing. If the projectile sticks out the bottom, it is too long and projectile needs to be set further into the shell (should be set to C.O.L.). If round head sticks out of top, the round needs to be disassembled for re-sizing (excessive crimp can cause shell distorsion) and crimp needs to be reduced. This gage is a FUNDAMENTAL tool for reloading.

It works as advertised, however the corners were all damaged probably from Poor handling while being shipped.

This is made to the MINIMUM SAAMI specs. It did not state that when I bought this a few years ago. I could not get it to accept factory ammunition new product from Remington among other companies. Not any of my reloads etc. But they all chambered in a .223 wylde and often a few different size and style .223 wylde barrels. I wrote to the manufacturer and he honestly said the only way to use the gauge was if you bought special undersize dies. I grew up and worked for ~ 30 years as a high precision machinist, now I’m a scientist at a leading university. If a gauge like this is made to minimum specs it means it’s useless. The reason for this is that SAAMI gives a minimum to maximum range for every dimension. If it’s made to all minimum specs nothing but undersized ammunition will pass inspection. Because you are constricting measurement to minimum sizes or less. But if it’s minimum your ammunition really should rarely fit this thing as your ammunition needs to be between minimum and maximum not below minimum. I’m not sure what’s going on but any machinist that knows what they are doing should understand that a gauge that only accepts minimum or smaller is not meeting the true SAAMI specifications. It’s only going to accept ammunition which is minimum in every single dimension. It’s for all purposes useless. Which is why mine ( which was also poorly shipped and beat up) has sat in a box of my reloading tools since I got it. I emailed the manufacturer and he is the one who told me I had to switch to undersized dies to use it. Meaning non SAAMI spec ammunition. This is not going to work for proper SAAMI spec ammunition.223, it will only accept below spec ammunition. Thus for most of us it’s useless. Unless you like shooting cartridges that are as loose fitting as a hot dog in a hallway.. have fun with that when it seizes the cases in your chamber as that’s what this will result in.

I reload a lot of .223 with mixed cases and multiple reloading. This standard lets me know that the loaded round will fit my chamber. This standard also gives a check on the over all length. Having multiple holes allows flexiblity and saves time. Great Value.
