Case Gauge Ammo Checker .40 S&W 7-hole Reviews

5 Rating 7 Reviews

Our Case Gauge Ammo Checkers are machined from solid 6061 T6 aircraft grade aluminum.Our gauges are made to SAAMI miniumum spec.While some companies use boring bars to make chamber checkers, we use the actual Clymer reamers that are used to chamber barrels.Anodized matte black for durability.Measures min case diameter.Measures max overall length. We have found our gauges extremely helpful when reloading ammunition. We recommend the following procedure to help alleviate any issues while reloading. The following information is general information and not caliber specific. We always recommend consulting your reloading manual:
Checking Case Length: Auto pistol cartridges headspace on the case mouth and not the case rim as revolver cartridges do. To make certain your cases are not too long, do the following:
1. Resize and deprime the case. 2. Drop the case inside the holes in our case gauge. 3. If your cases are flush with the top of the gauge, the cases do not need trimming. However, if they do protrude, then trimming may be required.
Checking Proper Bullet Seating Depth: 1. Install the bullet into a correct length case and drop it in to our gauge. 2. If the case is flush with the top of the gauge, the seating depth is correct (for that shape, style, length and weight bullet). 3. If the case protrudes slightly, remove the cartridge and reseat the bullet just a fraction of an inch deeper into the case and try again. If the case is still protruding, seat the bullet deeper and stop when the case sits flush with the gauge. 4. With the cartridge still in the gauge, hold it in place with your finger and turn the gauge over. The tip of the bullet should not protrude beyond the bottom of the gauge. If it does, the bullet is not seated deep enough and should be set deeper. 5. If the case has been properly resized, the length is correct, and the bullet is seated to the proper depth, you should be able to turn the gauge over and have your cartridge fall out by gravity alone.

“When reloading pistol or rifle cartridges,this is one of the last checks of how you did before putting them in a box and labeling them. If they do not fit in the guage they will not fit your weapon. Loading plated pitol bullets especially need checking because when seating the bullet,some slight bit of plating can be shaved off the bullet. This guage insures you catch any of these. You buy in bulk to save money and even if you are very careful loading,the bullets are not all the same dimensions. Years ago I had a bad batch of 45 acp that had about 30 rejects out of 500. I had bought them for years with no problems(Rainier). They are out of business. I have been using RMR bullets and Berrys.RMR are real jacketed bullets where Berrys are plated. Both are very good! For loading rifle bullets,I also check my cases for lenght etc. With a headspace guage .”

“Works perfectly. Is basically 7 .40cal chambers, made to the smallest dimensions allowed for chambers (SAAMI minimums) - so if your loaded round (or dummy round, setting up your dies) fits flush in this tool, it will fit any gun's chamber. If the base sticks out, you have an issue - possibly a bulged case (Glock brass perhaps), brass that has not been resized properly, brass that has not been trimmed to proper length, or a bullet that isn't seated deep enough. If the bullet sticks out the bottom, the bullet seating depth needs to be deeper. If the round comes out easily when you invert the checker, it'll fit any firearm of that caliber. I reload a lot of range pickup brass, and a few bulged handgun rounds caused me feeding issues during competitions. Bought this in 9mm Large Ogive (I reload primarily 147gr 9mm) and discovered several more bulged cases, which I then removed from my competition ammo supply. As soon as a round comes off my press, it goes into the checker - hundreds of rounds later, no more issues with Glock bulged brass causing feeding problems in my gun. Liked it so much I bought the same chamber checker in .223 Rem, which helped immensely in setting up my dies. Also bought it in .40, .45, and .30-06, great tool, don't know how I went so many years without it! I use fairly basic Lee 4-die sets with full-length resizer dies. As soon as a round comes off my press (or while initially setting up the resizing, powder charging, and bullet seating dies), it goes into the chamber checker. If it passes, it then goes into my match ammo supply. Since I've started using these checkers, I have had no feeding issues in any of the calibers I reload.”
