Lyman Ram Prime Priming System with Large and Small Punches

Precision Priming System

The Lyman Ram Prime is a bench-mounted priming tool that threads into any press with standard 7/8"-14 threads. It seats one primer at a time with controlled feel, helping reloaders achieve consistent depth across large and small calibres. Both punch sizes are included so the same unit handles every common primer type.

Reloaders Who Need Controlled Seating

Hand-loaders who value tactile feedback and repeatable primer depth will benefit from the sensitive, one-at-a-time action. The system suits anyone running a standard-threaded press and working across multiple calibres. Shooters who require high-volume automated priming or a press-mounted unit without thread adaptation should consider other designs.

7/8"-14 Thread Compatibility

The single specification that decides fit is the 7/8"-14 thread pattern, which matches virtually all modern reloading presses. If the press uses this standard thread the Ram Prime installs directly; if the press uses a different thread pattern the system will not mount without an adapter.
