Product Overview

The Lee 9.3x64 Brenneke Factory Crimp Die is purpose-built for shooters who demand dependable, repeatable ammunition performance from a powerful hunting cartridge. Designed to duplicate a true factory-style crimp, this die uses a collet system to squeeze the case mouth evenly into the bullet, locking it firmly in place without distorting the case. The result is ammunition that feeds smoothly, resists bullet setback under recoil, and maintains consistent overall length – critical advantages when you’re running a hard-kicking rifle or cycling rounds repeatedly through the chamber.

By creating a firm, uniform crimp, the Lee Factory Crimp Die helps build higher and more consistent start pressure before the bullet moves, which in turn promotes cleaner powder burn, tighter velocity spreads, and improved downrange accuracy. It’s especially valuable for heavy-recoiling 9.3x64 Brenneke rifles used in big game hunting, where reliable ignition and bullet retention can make the difference between a clean shot and a missed opportunity. Whether you’re fine-tuning a dangerous game load or simply want your handloads to match the reliability of premium factory ammo, this die offers a practical, field-proven upgrade to your reloading setup.

Key Features

• Factory crimp design firmly secures the bullet in place, helping ammunition handle reliably in both hunting and high-recoil shooting scenarios.

• Segmented straight crimp provides a strong, uniform hold on the bullet, improving consistency from round to round.
• Higher start pressure before bullet movement promotes a more uniform pressure curve and reduces velocity variation for better downrange accuracy.
• Effective even with bullets that have no cannelure, allowing more accurate loads across a wider range of projectiles.
