Most Helpful Positive Review Ammo Checker
It works. I never have any problems with my ammo when using this product. If it fits properly in the checker, it will chamber properly in my firearm. It is just that simple. I do a lot of reloading, and anyone that does a lot of reloading knows that sometimes a case may not line up perfectly. When that happens, the naked eye may not see it, but this device will catch the problem. Easier to catch it right out of the press than in the field.

exactly what i needed to guage my hand loads

by Darlon Sinclair, Verified Owner from MT, United States Written on July 8, 2025
What ever the description says about the build quality, it’s true. These are a must have if you hand load or you just wanna check to make sure factory rounds are within spec. I have them for all the calibers I load, for both rifles and pistol, you get what you pay for and are worth the cost. Thanks to optics planet for make it affordable for purchase here.
Pros:
  • Within specs
Cons:
  • None
Would recommend: Yes

Nice Chamber Checker

by Anthony Suarez, Verified Owner from MA, United States Written on February 14, 2024
Perfect for your loading needs. Reasonable pricing but not so quick shipping. Maybe I'll opt for the 100rd checker.

Chamber Checker for Reloaders

by Mudrigg, Verified Owner from CA, United States Written on January 24, 2021
Have used this chamber checker on 100's of rounds of reloads. I can not only check the OAL but you can tell if the round itself is a bit tight too in order to see if any rounds my be susceptible to sticking in the chamber of the rifle. I recommend it as a safety check for all reloaded rounds prior to firing. Very durable/built sell

Evolution Gun Works Ammo Chamber Checker

by Gary, from LA, United States Written on May 31, 2017
Bought one in .300 AAC and .308 Win. Already had one in .223/5.56
These make checking sized cases a breeze! Straight out of the sizing die into the block x7, then empty and go again. Increases productivity by not having to stop for every piece of brass. A must have for the volume reloader.

EGW Chamber Checker

by aispir2, from OH, United States Written on April 30, 2017
Great product, arrived on time in great condition. I have this chamber checker in several calibers now and they all work great. Very easy to use and takes up very little space on the reloading bench. I end up checking every round.

Slow shipping, great product

by E, Verified Owner from WI, United States Written on March 14, 2017
Don't choose value shipping if you want your product in a timely fashion. It took two days to pull my order and seven days to ship 275 miles. I can drive there in 4 hours. Chamber checker is great use it all the time, wouldn't reload without one.

Chamber Checker

by Dennis, Verified Owner from CT, United States Written on March 6, 2017
I purchased three of these, one for 380 ACP, one for 9 mm,one for 45 ACP they each hole seven rounds and when they drop right in and fall right out I feel pretty confident that they will work in my pistols. I do use a micrometer to measure the length and width, once it's set it pretty much stays there. I do recommend this product

Ammo Checker

by Hal, Verified Owner from TX, United States Written on October 30, 2016
Does it job perfectly. As a beginner re-loader I wanted to make sure my cartridges were up to snuff and this is a quick and easy way to verify sizing. The product is quite solid, made of high grade material and is easy to use.

50 round .45 ACP EGW Chamber Checker

by Brent, from TX, United States Written on October 4, 2016
I bought the 50 round .45 version. Like anything EGW, it shows quality in the way it feels, is finished, and operates. This gauge makes checking fit and verifying primer depth so much more convenient and is fast, pays for itself in time saved. I think it a bit handier size than the Shok-Bottle 100 size, the EGW 50 might be handier to use when dumping rounds into a GI can. A 9mm version is definitely next on my list, watching for a sale or coupon.
Pros:
  • None
Cons:
  • Bit expensive
Would recommend: Yes
