Spare undersized Universal Decapping Pin - Lee

The Essential Lee Precision Undersized Flash Hole Universal Decapping Pin

This specialized decapping pin from Lee Precision is specifically designed for cases with undersized flash holes. With a diameter of 0.057" (1.45mm), this pin is thinner than the standard 0.062" version, allowing you to work effortlessly with European cases like Lapua, Norma, and other premium brands that utilize smaller flash holes.

Why This Undersized Decapping Pin Is Indispensable

The Lee Undersized Flash Hole Universal Decapping Pin solves a common problem in precision reloading. Many European cases, especially those used for benchrest and F-Class disciplines, feature smaller flash holes for improved consistency and accuracy. A standard decapping pin simply won't fit, causing your reloading process to stall. This specialized pin enables you to process these high-quality cases without damaging the flash hole or the pin itself.

This replacement pin is compatible with the Lee Universal Decapping Die (#90292) and the Undersize Flash Hole Universal Decapping Die (#91976). The hardened steel construction ensures durability, though caution is still advised with Berdan primers or cases with off-center flash holes.

Practical Applications for Precision Shooters

For shooters working with 6mm BR, 6.5x47 Lapua, .220 Russian, or other precision calibers using Lapua or Norma cases, this pin is essential. You'll also encounter undersized flash holes regularly when reloading certain batches of 9mm cases from European manufacturers.

The pin is particularly valuable for competitive shooters in F-Class, benchrest, and ELR disciplines where every detail matters. Using the correct decapping pin prevents damage to your premium cases and maintains the uniformity crucial for consistent long-range shooting results.

Usage Tips for Optimal Results

Always verify which type of flash hole your cases have before beginning the decapping process. Measure the diameter with a pin gauge if necessary. If you encounter resistance during decapping, never force it but check whether you're using the correct pin. An incorrect pin can damage both the case and the tool.

Keep spare pins in stock at all times. Although these pins are made from hardened steel, they can still bend or break with intensive use or when accidentally hitting off-center flash holes. For high-volume reloaders, it's smart to purchase multiple pins immediately.
