RCBS 87305 Stainless Steel Multi-Caliber Dial Caliper

The RCBS 87305 Stainless Steel Multi-Caliber Dial Caliper is a precision measurement tool built for handloaders who demand accuracy when working with brass, bullets, and loaded ammunition. Whether you're developing loads for a new rifle, verifying case lengths, or measuring bullet seating depth, this dial caliper delivers the repeatability that separates good reloading from great reloading. Its hardened stainless steel construction and matte finish won't glare under bright bench lighting, and the shockproof dial movement means your measurements stay true even if the tool takes a bump.

With a 0–6 inch measurement range and 0.001-inch graduations, the RCBS dial caliper splits the difference between ease of use and genuine precision. The four-way measurement capability—inside, outside, depth, and step—covers the tasks most reloaders encounter daily: checking case length, verifying bullet seating, measuring neck diameter, and confirming overall cartridge length. The dial reads directly at 0.100-inch per revolution, so you won't be hunting for tiny numbers on a vernier scale after a long session at the press.

User-friendly details matter in reloading. A thumb wheel opens and closes the jaws smoothly, the slide locks firmly with a thumb screw to hold your measurement in place, and the dial zeroes easily and locks to prevent drift. A protective lens covers the dial face to keep dust and scratches away from the measuring surface. The included hard plastic storage case keeps the caliper organized and protected between sessions.

Accuracy is held to ±0.001 inch—tight enough for the precision reloading demands, whether you're a competitive shooter, a long-range hunter, or simply someone who respects the process of making ammunition that performs.
