Lee Precision 90210 Shell Holder #10 for Auto Prime Press System

The Lee Precision 90210 Shell Holder #10 delivers precise cartridge positioning for the Auto Prime Press system. This shell holder accommodates specific cartridge sizes with exact tolerances that ensure consistent priming operations. Built from hardened steel, it maintains dimensional stability through thousands of reloading cycles.

What Makes This Different

Unlike universal shell holders that compromise on fit, the #10 shell holder features cartridge-specific dimensions machined to SAAMI specifications. The hardened steel construction resists wear from repeated case insertion and extraction cycles. This precision manufacturing eliminates case head movement during priming, reducing the risk of primer seating inconsistencies that can affect ignition reliability.

Key Features

• Hardened steel construction for extended service life
• SAAMI specification dimensions for precise cartridge fit
• Compatible exclusively with Lee Auto Prime Press systems
• Accommodates .270 Winchester, .30-06 Springfield, and similar rim diameter cartridges
• Heat-treated surface resists deformation under pressure
• Machined tolerances within 0.001 inches for consistent performance
• Numbered identification system prevents mix-ups during reloading sessions

Reloaders processing high volumes of .270 Winchester or .30-06 Springfield cartridges benefit from the shell holder's consistent case positioning. The precise fit eliminates case movement during primer insertion, resulting in uniform primer seating depth. Competition shooters and hunters who demand reliable ignition find this consistency translates to improved accuracy and reduced misfires. The hardened steel construction maintains these tight tolerances even after processing thousands of cases.
