The Lyman Ammo Checker Block 9mm 100 Hole is a go/no-go gauge designed to let handloaders verify chamber fit before firing. Built from solid 6061 T6 aircraft-grade aluminum and machined to SAAMI minimum chamber specifications, this tool eliminates the guesswork—simply drop a loaded round into the appropriate hole, and if it seats fully, it will chamber in your firearm. For any reloader working up 9mm loads, it's a quick, tangible way to catch out-of-spec rounds before they hit the range or field.
The block features 100 holes sized specifically for 9mm, giving you plenty of room to test a full reload session without moving the gauge. Bright orange anodizing makes it hard to lose among powder scales, calipers, and dies, and each caliber marking is clearly engraved so there's no confusion in a busy bench setup. Unlike digital scales or calipers that measure diameter, this is a direct fit-check—the most reliable way to verify your ammunition will actually cycle smoothly in your chamber.
Whether you're fine-tuning a new load, troubleshooting a batch of rounds, or just want a final visual confirmation before range day, the Ammo Checker Block takes seconds to use and removes doubt. It's the kind of simple, rugged tool that pays for itself the first time it catches a slightly oversized or out-of-spec case before a firing pin strike.
| Caliber | 9mm |
| Hole Count | 100 |
| Material | 6061 T6 Aircraft-Grade Aluminum |
| Design | Go/No-Go Gauge Block |
| Machined To | SAAMI Minimum Chamber Dimensions |
| Finish | Bright Orange Anodizing |
Simply drop a loaded round into one of the 100 holes. If the cartridge fits fully into the hole, it will fit in your firearm's chamber. If it doesn't fit or gets stuck, the round is out of spec and should not be fired.
No, this block is machined specifically to SAAMI minimum specifications for 9mm. Each caliber requires its own dedicated gauge block.
It complements them rather than replaces them. Calipers measure dimensions; the Ammo Checker Block verifies actual fit in a SAAMI-spec chamber. Both tools together give you confidence in your reloads.
More holes let you test a full batch of reloads without constantly removing the block, making it faster and more practical for high-volume handloaders.
