Designed to verify chamber compatibility for a wide range of popular handgun and rifle calibers, these durable tools ensure reloaders can quickly and accurately confirm their ammunition fits perfectly, reducing misfires and enhancing shooting performance. ## Description Lyman - an innovator in the field of reloading and shooting accessories - has introduced their Cartridge Checkers. These gauge blocks allow reloaders to quickly confirm that their ammunition will fit in their chamber. Made from solid blocks of 6061 T6 aircraft grade aluminum, each of the three orange anodized Cartridge Checkers are precisely machined to SAAMI minimum chamber dimensions and accept the most popular rifle and pistol rounds. Simply drop a loaded round into the clearly marked cartridge hole. If it fits flush with the top of the gauge, the round will chamber. Checkers are available in three designs covering most common handgun and rifle calibers. Handgun gauge: 380 Auto, 9mm Luger, 38 Super, 40 S&W, 45 ACP, 38/357, 44 Mag/Spl, and 45 Colt Small Rifle gauge: 204 Ruger, 22 Hornet, 223 Rem, 22-250, 300 AAC Blackout and 7.62x39mm Large Rifle gauge: 243 Win, 270 Win, 30-30 Win, 308 Win, 30-06 and 300 WSM.

I just tried and a deprimed and sized .223 casing dropped in flush with the top surface and came out easily, while unsized brass stopped about 1/8" out (it could be forced in but had to be poked out with a hex wrench.) Note that this gauge ONLY checks whether the round will chamber, it does not check for overall length. **Q: If I have some 44 mag and 44 S&W will it help to tell the difference? or 10mm and 40 S&W. Both have the diam, but different depths. thanks** A: No it does not, I have both and it will tell you what its bored for. Brass is mark on back of rim to know which brass is which. 40\10mm are same CIA. But major length diff. 44 mag and 44swor special are closer.... **Q: Do you have the 9mm Luger 100 cartridge checker?** A: No ## Customer Reviews ### ⭐⭐⭐⭐⭐ Quality *by L***O on February 13, 2026* Good quality ### ⭐⭐⭐⭐⭐ Great for checking finished rounds *by G***G on January 11, 2026* Exactly what I needed. Multiple calibers and works as advertised. ### ⭐⭐⭐⭐⭐ CAREFULLY MEASURED, LOOKS GREAT FOR 9mm *by W***S on September 11, 2017* So far I've only checked the 9mm hole, but what I see is fine. I used plug gages to measure diameter and depth (They're all 2.00" long). SAAMI spec for 9mm is 0.3913" dia measured in from the breech face 0.200". I used a 0.392 minus gage (0.39195" measured with Mitutoyo QuantuMike) and it went into the 9mm hole in the gage I just received 0.201". So this looks right on. I noticed that, like my Glock barrel, this hole on the gage is tapered.On my block, the top of the hole is about 0.395", and down at the bottom (there's a ridge that stops the shell from going in any farther) it's about 0.382" (again this is approx as there is a small radius at the bottom of the hole that makes plug gages a few thousandths larger stop a little early). You can see this taper easily by dropping in a shell "upside down". The rim on a new Starline shell is about 0.387, and if dropped in that way it doesn't go all the way to the stop, implying that the dia is 0.387 most of the way down the hole. Other reviewers have mentioned other issues, which I will comment on here. The item I received in mid Sept '17 DID have the calibers marked on the top. Also for those that mentioned that it didn't check for cartridge length, since mine had the ridge at the bottom (I'm calling it the "stop") I decided to check where that stop was. Dropping that same new Starline shell, which had an overall length of 0.748" (SAAMI recommends 0.744"-0.754") into the Lyman gage stopped with the top of the shell about even with the top of the gage (+/- 0.002"), so I think you could also use this current delivered gage to check shell length. So overall I concluded that this gage, at least for the one hole, 9mm, I checked to be right on, and a good tool for checking what it is designed to check. Previous reviewers have mentioned that loaded cartridges that fit into the gage would not chamber in their pistols. My Glock 19 (circa 1985), when checked with a plug gage, had a chamber diameter of 0.391 about 0.200" in from the breech face, so I feel that if a cartridge fits in the gage it will chamber ok in the Glock. I have not actually tried shells that won't fit in the gage to see if they will chamber, but the math says that this gage will tell me if my reloads will cycle properly in my Glock. SUMMARY: For the 9mm bore, this gage is SPOT ON. ## Frequently Bought Together - Lyman Ammo Checkers - Ludex Ammo Checkers Ammo Checker Cartridge Gauge for Reloading (ammo checkers, orange) - Lyman Single Caliber Rifle Ammo Checkers --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ie/products/24692996-lyman-ammo-checkers](https://www.desertcart.ie/products/24692996-lyman-ammo-checkers) --- *Product available on Desertcart Ireland* *Store origin: IE* *Last updated: 2026-04-23*
