Works fantastic just like the 9mm 7hole I already Jesse

Worked perfectlly.

Solid, dependable, reasonably priced - what else could you want?

Works perfectly. Is basically 7 .45cal 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.

Like everything from EGW, my .45 ACP case checker is thoughtfully designed and well finished. It is a very handsome and useful tool to have. I first used it last night and was pleased from the start.
