The MEC 1311079 Digital Caliper brings precision reloading measurement to your bench. Whether you're checking brass dimensions, verifying cartridge overall length, or dialing in case specifications, this digital caliper delivers the accuracy serious handloaders need. It measures in both inches and millimeters, so you can work with load data in either system without conversion headaches. The locking screw lets you hold a measurement steady while you work—no need to babysit the display when you're comparing multiple rounds or setting up repeatable specifications.
Built by MEC Reloading in the USA, this tool is engineered for the consistency that reloading demands. With a measuring range from 0 to 6 inches (0–150mm), it covers everything from small-rifle cases to magnum rounds. The accuracy of ±0.001" (0.02mm) and repeatability of 0.0005" (0.01mm) means your measurements stay tight shot after shot—critical when you're trying to squeeze performance and safety out of your handloads.
Reloaders who care about precision recognize that quality measurement tools are foundational. This caliper earns its place on the bench next to your press, scale, and case prep station, letting you catch dimensional drift before it becomes a problem.

Frequently Asked Questions
What can I measure with this digital caliper?
Use it to measure brass dimensions, cartridge overall length, case neck wall thickness, bullet diameter, and any other reloading specification that falls within its 0–6 inch (0–150mm) range. The locking screw makes it easy to hold a measurement while you set up your press or compare multiple samples.
Can I use this caliper for both inches and millimeters?
Yes. The display toggles between inches and millimeters, so you can read your load data in whichever unit system it's published in without doing conversions on your calculator.
How precise is this caliper for reloading work?
With an accuracy of ±0.001 inch (0.02mm) and repeatability of 0.0005 inch (0.01mm), it's precise enough to catch dimensional drift in your cases and verify that your handloads stay within specification. That level of consistency matters when you're chasing accuracy or working close to pressure limits.
Is this caliper made in the USA?
Yes. The MEC 1311079 is manufactured in the USA, consistent with MEC Reloading's commitment to making their entire product line domestically.
