MEC RELOADING · Digital Caliper · MPN 1079
Compare cases and cartridges up to 150 mm with controlled precision
The MEC 1079 measures external, internal, and depth dimensions, switches between millimeters and inches, and locks comparison positions. For reliable results, zero point, measuring pressure, and a clean contact surface are crucial.
0–150 mm · 0.01 mm resolution
Black-Raptor Purchase Check
The caliper covers typical length and diameter checks at the reloading bench. It is not a headspace gauge, cartridge chamber gauge, or micrometer for tighter tolerances.


Fits well
for case length, overall length, and diameter comparisons;
when mm and inches need to be switched directly;
for series measurements with consistent, light pressure.



Less suitable
as a caliber-specific headspace or cartridge chamber gauge;
for measurements below the specified accuracy limit;
on dirty, hot, or still burr-covered workpieces.



Practical Use


Three measurement types—external, internal, and depth—can be checked with one tool.


Unit Selection Direct mm/inch switching avoids unnecessary conversion.


Locking Screw One position can be secured for quick comparison checks.


150 mm Range The range covers many typical case, cartridge, and workshop dimensions.


Avoid Limits, Disadvantages, and Bad Purchases
0.01 mm is the resolution; the current spe
zifikation nennt ±0.02 mm accuracy. Angled positioning, varying pressure, and burrs distort values. Suitable comparator inserts are required for shoulder or ogive reference measurements.

Frequently asked questions
Does it measure in mm and inches? Yes, the display is switchable. Is 0.01 mm the accuracy? No. That is the resolution; specified accuracy is ±0.02 mm. Can it measure headspace? Only with a suitable additional reference system; alone it is not a headspace gauge. What is the locking screw for? It holds a slider position for comparative measurements.
BR classification: A versatile measuring tool for the loading bench. Its quality only shows with clean, repeatable use and suitable additional gauges.
