Lee Undersize Mandrel .262 For 6.5X55 .260 Remington & 6.5 Creedmoor

The Lee Undersize Mandrel .262 for 6.5x55, .260 Remington, and 6.5 Creedmoor is a precision reloading component designed for shooters who demand tight, consistent case neck sizing. This mandrel-style sizing tool is purpose-built for rifle cartridges favored by long-range precision shooters, hunters, and military/law enforcement marksmen. Unlike full-length sizing dies that can distort case necks, the undersize mandrel approach preserves case concentricity and extends brass life—critical factors when building match-grade ammunition or when ammunition availability is limited in field operations.

The .262 mandrel diameter is engineered to size necks slightly undersized, allowing loaded rounds to chamber with minimal runout and maximum accuracy potential. Lee Precision mandrels are manufactured from hardened steel and designed to work within standard reloading presses using Lee's mandrel sleeves or compatible die setups. The undersize specification ensures that when a bullet is seated, the neck tension remains consistent and true, reducing vertical stringing and improving shot-to-shot precision—essential when shooting at distance or in duty situations where every round counts.

Precision rifle competitors, long-range hunters, and tactical reloaders benefit most from this mandrel, particularly those working with 6.5x55 Swedish, .260 Remington, and 6.5 Creedmoor cartridges. The compact 3.25-inch overall length integrates seamlessly into existing reloading benches without requiring specialized equipment, making it an ideal choice for those looking to enhance their reloading process.
