Lee Precision 90212 Shell Holder AP Only #12

The Lee Precision 90212 Shell Holder #12 is a dedicated hand-priming accessory designed specifically for use with Lee's Auto Prime tool. If you're setting up a compact bench-top priming station separate from your reloading press, this shell holder gives you a purpose-built, efficient way to prime brass by hand without needing a full press setup. The #12 size accommodates a specific range of cartridges, making it an essential component for reloaders who want flexibility in their workflow.

Hand priming offers real advantages for many reloaders: it isolates the priming operation, reduces fatigue on a press-mounted system, and lets you inspect and prep each case carefully before seating a primer. Lee's shell holders are engineered to hold cases securely while you work with the Auto Prime, so cases stay centered and primers seat consistently. This isn't a universal holder—it's sized and designed exclusively for the Auto Prime tool, which keeps things simple and reliable.

Lee Precision has been manufacturing reloading equipment for decades, and their shell holders reflect that experience. The #12 is one of 20 unique sizes in the Lee lineup, so whether you're working with rifle or pistol cartridges, there's a holder tailored to your needs. If you reload multiple cartridge types, you can build out your collection incrementally, or explore Lee's shell holder kits if you want to cover a wider range of rounds in one go.

Is the Auto Prime tool included?
