The Lyman Ammo Checker Single Caliber 350 Legend is a straightforward quality-control tool for reloaders who want to verify their ammunition will actually fit and fire in their rifle. This case gauge cuts through the guesswork by letting you test-fit each round before you load it into the magazine—if your cartridge drops into the checker, it'll chamber in your gun. It's built from solid aluminum and machined to SAAMI minimum chamber tolerances, so you're working with spec-accurate dimensions that match real firearms, not approximations.
Whether you're working up loads for your 350 Legend hunting rifle or building match-grade rounds for the range, consistency matters. The Ammo Checker catches dimensional problems early—too-long cartridges, out-of-spec shoulders, or bulges from a press mishap—so you don't waste components and don't risk a stuck case or a firearm malfunction downrange. It's the kind of simple, practical tool that pays for itself in saved ammunition and peace of mind.
Each gauge is clearly labeled for its caliber and finished in bright orange anodizing, so it won't get lost in the shuffle of your reloading bench. This is the single-caliber 350 Legend model, designed exclusively for that cartridge.

Frequently Asked Questions
Will this Ammo Checker work with both reloaded and factory 350 Legend ammunition?
Yes. The gauge is designed to verify the quality and consistency of any ammunition in the 350 Legend caliber, whether you handloaded it or bought it factory-fresh.
What does it mean if a cartridge doesn't fit in the checker?
If a round won't drop into the gauge, it won't chamber reliably in your rifle either. This tells you the cartridge has an issue—it may be too long, have a bulged case, or have other dimensional problems. Set it aside and figure out where the problem came from in your reloading process.
Can I use this gauge for other calibers?
No. This is a single-caliber tool made specifically for 350 Legend. It will not work with other cartridges.
How do I use it?
Simply drop each finished cartridge into the gauge. If it fits without resistance, it will chamber in your firearm and is good to load. If it sticks or won't drop in, the round has a dimensional problem and should not be fired.
