Hornady Lock-N-Load Cartridge Gauge 30-30 Win Silver

The Hornady Lock-N-Load Cartridge Gauge is a precision SAAMI-spec fitting tool for handloaders working in 30-30 Winchester. Drop a finished round or a resized case into the gauge; if it seats flush, your case dimensions and headspace are within spec and the load will fit a standard .30-30 Win chamber. If it doesn't, you'll know to make adjustments before that ammo ever sees the range.

Machined from steel and finished in silver, this gauge is built to live on the reloading bench. It joins Hornady's Lock-N-Load line of precision measuring and gauging tools, giving reloaders a fast, simple way to verify fit without having to chamber-test every round in the actual firearm.

Use the gauge during case setup to confirm resized 30-30 Win brass is trimmed and sized correctly, and to sanity-check handloads before they're loaded into a tubular magazine or single-shot rifle. It's a small, affordable step that helps prevent hard chambering, sticky bolt lift, and feeding problems at the range.
