Precision rimfire reloading starts with consistency, and the Hornady Lock-N-Load Thickness Gauge for 17-22 caliber rimfire cartridges gives you a practical way to sort ammunition by rim thickness — a sorting method that's been shown to tighten accuracy downrange. If you're working with .17 HMR, .17 HM2, .22 LR, or .22 Magnum ammo, this gauge lets you quickly identify and group rounds by rim spec, so your loads perform more uniformly shot to shot.
The tool works by attaching to the blade of a standard 6-inch caliper, turning a measuring instrument you likely already own into a specialized sorting tool. Hornady includes bushings sized for all .17 and .22 rimfire calibers, so you're covered whether you're prepping high-velocity magnums or standard .22 LR for precision rifle work. The straightforward design means you can process ammo batches quickly without fussy setup or learning curve.
Rimfire accuracy is a game of small margins, and rim thickness variation — even within factory lots — can shift point of impact and group size. Shooters chasing tight groups at the range or looking to maximize consistency in their handloads will appreciate a tool that brings that variable under control. It's a small investment in ammunition sorting that pays dividends when you're after repeatable performance.

Frequently Asked Questions
What calipers does this gauge work with?
The Hornady Lock-N-Load Thickness Gauge attaches to 6-inch calipers, so you'll need a caliper of that length to use it.
Which rimfire calibers can I sort with this gauge?
The gauge includes bushings for .17 HMR, .17 HM2, .22 LR, and .22 Magnum ammunition.
How does sorting ammo by rim thickness improve accuracy?
Rim thickness variation can affect how a rimfire cartridge seats and feeds, which impacts consistency. Sorting ammo into groups of similar rim thickness helps ensure more uniform performance from shot to shot.
Do I need special tools to use this gauge?
You'll need a 6-inch caliper. Once you have one, the gauge simply attaches to the caliper blade, and you use the included bushings to sort your ammo.
