Reloading ammunition is a precise process demanding accuracy at every step. Using the right tools is paramount, and among the most crucial is a high-quality caliper. Choosing the wrong one can lead to inconsistent rounds, safety issues, and wasted components. This guide will help you navigate the market and select the best calipers for your reloading needs.
Types of Calipers for Reloading
Before diving into specific recommendations, understanding the different types of calipers available is essential. Each offers unique advantages and disadvantages:
1. Dial Calipers:
- Pros: Offer high precision, often reading to 0.001" (or 0.01mm), and are relatively inexpensive. The dial provides a quick and easy reading.
- Cons: Can be slightly less durable than other types and prone to damage if dropped. The dial mechanism can be less precise over time due to wear and tear. They are also not ideal for measuring irregular shapes.
2. Vernier Calipers:
- Pros: Known for their durability and accuracy, often matching the precision of dial calipers. They tend to be more robust and less susceptible to damage from drops.
- Cons: Reading vernier calipers requires a bit more skill and understanding than dial calipers, as you need to interpret two scales to obtain the measurement.
3. Digital Calipers:
- Pros: Provide a clear digital readout, eliminating the need to interpret scales. They typically offer high precision and are easy to use.
- Cons: More expensive than dial or vernier calipers, and the battery can die at an inopportune time. The electronic component can also be more sensitive to damage.
Factors to Consider When Choosing Reloading Calipers
When selecting calipers for reloading, several critical factors should guide your decision:
1. Precision and Accuracy:
- Look for calipers with a resolution of at least 0.001" (0.01mm) for accurate case measurement and bullet diameter checks. Higher precision is beneficial for more demanding reloading tasks.
2. Size and Range:
- The caliper's measuring range should accommodate the largest cartridge cases you'll be working with. Ensure the jaw opening is sufficient.
3. Durability and Material:
- Choose calipers made from durable materials like hardened stainless steel for long-lasting performance. A robust build can withstand the rigors of frequent use.
4. Features:
- Consider features like a zero-setting function for easy reference points, locking mechanisms to hold measurements securely, and a depth gauge for measuring case depth.
