Frankford Arsenal Dial Caliper For Reloading

Frankford Arsenal’s stainless steel dial caliper is designed for reloading tasks on and off the bench. It offers accuracy within .001″ for measuring case length, neck and base diameters, overall length, and primer pocket depth across a 0-6″ range. The durable stainless steel construction resists wear during frequent use, making it a solid choice for ongoing reloading workflows where consistent readings are essential.
HFS 0-6″ Imperial Dial Calipers

These 0-6 inch Imperial dial calipers from Hardware Factory Store emphasize a double shock-proof design and high-accuracy readings. Made of polished stainless steel, they provide precise, repeatable measurements with a range of 0-6 inches, accuracy of ±0.001″, and a 0.001″ division. The robust build and smooth sliding action support both routine and meticulous cartridge-length checks.
Hornady Dial Caliper For Reloading

The Hornady Dial Caliper is a dedicated reloader’s tool designed to measure case and bullet length, inside and outside diameters, primer pocket depth, and overall cartridge length with 0.001″ accuracy. The 6-inch dial, shock-resistant construction, and included storage case make it a reliable companion for field use and bench sessions alike, supporting precise load development and quality control.
Lyman Stainless Caliper

Lyman’s stainless caliper is a long-trusted option among reloaders, offering solid construction and dependable performance. While compact in description, its stainless build helps durability during repeated measurements of case length and diameters. This model suits reloaders who prefer a straightforward, proven tool for everyday use on the reloading bench.
NEIKO 01407A Electronic Digital Caliper

NEIKO’s 01407A is a digital caliper with a 0-6 inch range, offering quick inch/millimeter/fraction conversions via a large LCD. While not a dial caliper, it provides versatility for reloaders who need rapid unit changes, depth measurement, and easy zeroing. Its splash- and dust-resistant body adds resilience for messy reload setups or outdoor bench work.
Buying Guide: Key Purchase Considerations
- Accuracy and resolution: For reloading, look for calipers with 0.001″ resolution and guaranteed accuracy around ±0.001″ to ensure consistent measurements for case length, neck diameter, and overall cartridge length.
- Construction and durability: Stainless steel bodies resist corrosion and wear. A robust dial or digital mechanism helps maintain accuracy after repeated use.
- Measurement needs: Dial calipers excel in hands-on bench use with quick, tactile readings. Digital calipers offer easy unit conversions (inch/mm/fractions) and quick zeroing, which is useful for field work or quick checks.
- Portability and storage: A protective case is beneficial to prevent damage in transport or on cluttered benches. Consider models with included cases for safe storage.
- On-bench vs. off-bench use: If you frequently move between the reloading bench and other work areas, a durable, easy-to-read caliper with a reliable lock is preferred.
- Brand and support: Reputable brands like Hornady, Frankford Arsenal, Lyman, and NEIKO typically offer better long-term service, replacement parts, and user confidence for critical measurements.
- Maintenance: Regularly clean the jaws and sliding surfaces, verify zero alignment, and recalibrate if readings drift, especially after exposure to dirt or oil.
When selecting a dial caliper or a compatible measuring tool for reloading, balance the need for readability, durability, and the type of measurements you perform most often. Dial calipers provide direct, immediate feedback on the bench, while digital options can streamline conversions and data recording, particularly in field setups or integrated reloading workflows.
