What is the measuring range and accuracy of the Hornady 050080 Digital Caliper for reloading?

The Hornady 050080 digital caliper provides a measuring range of 0 to 6.0 inches (0 to 150mm) with an accuracy of plus or minus 0.001 inch (0.02mm). It features an extra-large LCD screen displaying measurements down to .001 inch, making it ideal for checking case lengths, bullet seating depths, and primer pocket depths.

Does the Hornady Digital Caliper require any special electrical certification or compliance marks for use in Australia?

As a low-voltage DC battery-operated hand tool powered by a single 1.55V button cell, it does not connect to 240V mains power. Therefore, it does not require Australian SAA approval or mandatory RCM electrical safety compliance marks, making it ready to use straight out of the box.

What type of battery does the Hornady 050080 use, and are replacement batteries easy to find in Australia?

The caliper operates on a standard 1.55V silver oxide button cell battery (commonly compatible with SR44, LR44, or 357 types) and includes an automatic shutoff function to preserve battery life. Replacement cells are widely available across Australian supermarkets, hardware stores, and battery specialty retailers.

How should I store and maintain the Hornady 050080 caliper to protect its digital display and stainless steel frame?

The caliper is constructed from hardened stainless steel for long-term durability on the reloading bench and comes with a custom-molded protective hard case for safe storage. Because electronic tracks and digital displays can drift when exposed to excessive moisture, cutting fluids, or extreme temperature fluctuations, it is best kept in its protective case in a clean, indoor reloading environment.

Q: Can this caliper be used with Hornady comparative accessories like bullet comparators and headspace gauges?

Yes, the standard 6-inch jaws of the Hornady 050080 caliper are fully compatible with Hornady Lock-N-Load bullet comparators, headspace comparator anvils, and rim thickness gauges. This allows you to easily clamp these attachments onto the jaws for precise comparative measurements.

The Hornady 050080 Digital Caliper is a dedicated precision handloading tool engineered for firearm bench work, brass preparation, and ammunition assembly. Featuring a durable stainless steel frame, a smooth thumb adjustment wheel, and a top locking screw, it provides accurate dimensional feedback across an operating range of 0 to 6.0 inches (0 to 150–160 mm). It delivers exact readouts on an extra-large LCD screen with quick readout speeds, enabling handloaders to reliably measure internal diameters, external diameters, cartridge overall length (C.O.A.L.), trimmed case length, primer pocket depth, and shoulder datum distances. The caliper also features standard jaws compatible with Hornady Lock-N-Load bullet comparators, headspace comparator anvils, and rim thickness gauges.

Who is the Hornady 050080 Digital Caliper for?

Precision rifle handloaders — requires a measuring range of 0 to 6.0 inches with 0.001-inch accuracy to verify critical cartridge overall length (C.O.A.L.) and ensure consistent case trim lengths using this digital reloading caliper.
Benchrest shooters — relies on the 0.001-inch resolution and instant zero-setting capability of this digital reloading caliper to check bullet diameters and measure headspace datum distances when paired with comparator anvils.

Less suitable for: Measuring components exceeding 6.0 inches in length, which require a larger 8-inch or 12-inch digital caliper; or applications requiring sub-thousandth precision down to 0.0001" for neck wall thickness sorting, which require a dedicated ball-micrometer.
