LYMAN · Digital Caliper · MPN 7832218
Control measurement instead of estimation – measure inside, outside, and depth
The Lyman Digital Caliper covers measurements up to 150 mm and switches between millimeters and inches. It’s a handy tool for case and cartridge checks but no substitute for clean measuring surfaces and a repeatable technique.
0–150 mm · digital readout
Black-Raptor Purchase Check
The caliper suits users who want to quickly compare lengths, diameters, and depths. What’s especially important is not just the display value but always the same measuring pressure and a clean zero point.


Fits well
for outside, inside, and depth measurements at the reloading bench;
when switching between mm and inches;
for comparison and control measurements with documented reference.



Fits less well
when lab or micrometer precision is required;
for dirty, hot, or still burr-covered workpieces;
when a caliber-specific headspace or ogive insert is needed.



What the product practically brings you


Three measuring types Outside dimensions, inside dimensions, and depths can be checked with one tool.


Direct unit selection Switching between millimeters and inches avoids manual conversions and typical transfer errors.


Quick comparison Series of cases or cartridges can be quickly checked against a target or reference value.

Limits, Drawbacks and Avoiding Bad Purchases
The digital display doesn’t automatically make a measurement correct. Angled positioning, varying pressure, burrs or dirt distort results. Suitable comparator inserts are needed for shoulder and ogive measurements; never base safety-relevant decisions on a single measurement.
Technical Data with Practical Consequences


Measuring range 0–150 mm; covers typical workshop and reloading dimensions

Reading 0.01 mm; this is the display resolution, not a guaranteed overall measurement uncertainty

Functions Outside, inside and depth; always position cleanly and at right angles

MPN / GTIN 7832218 / 011516522184; with case and SR44 battery according to product assignment

Frequently Asked Questions
Does it measure in inches and millimeters? Yes, the display can be switched. Can I measure the bullet ogive with it? Only with a suitable additional comparator insert. The caliper alone measures at its jaws. Is a single measurement enough? For critical dimensions, zero point and value should be checked repeatedly.
BR classification: A versatile control tool for the reloading bench. The added value comes from clean routine – not just the number on the display alone.
