Lee Sizing Kit .311

The Lee Sizing Kit .311 is a precision bullet sizing and lubrication system designed for reloaders who demand efficiency and accuracy in cast bullet preparation. This Lee Precision sizing kit uses standard 7/8x14 thread compatibility, allowing it to mount directly onto any standard reloading press without modification. The system streamlines the entire sizing workflow by combining lubrication and sizing operations in a single, integrated process.

The .311 sizing die accepts bullets nose-first, eliminating the need for special nose punches—a design choice that reduces setup complexity and potential for damage to bullet noses. The kit automatically seats and crimps gas checks during the sizing stroke, ensuring uniform pressure rings and consistent bullet performance downrange. Sized bullets drop directly into the integrated capture container, keeping your bench organized and reducing handling time between sizing and loading. This design reduces contamination risk and speeds overall reloading throughput for high-volume shooters.

The Lee Sizing Kit .311 is built for handloaders who cast their own bullets or work with cast bullet suppliers. It addresses the specific needs of precision rifle shooters, cowboy action competitors, and high-volume target shooters who rely on cast ammunition for cost efficiency and consistent performance. The .311 diameter makes it ideal for preparing bullets for .308 Winchester, .30-06 Springfield, and related cartridges that benefit from the accuracy and economy of quality cast projectiles.

Lee Precision sizing kits remain industry standards for the reloading community, valued for their straightforward engineering and reliability across thousands of reloading sessions. This .311 kit maintains that reputation by combining fast operation with the precision bullet sizing that matches modern loaded ammunition standards.
