RCBS Rock Chucker Supreme Single Stage Press with Small Primer Plug, Sleeve, and Spring

The RCBS Rock Chucker Supreme single stage press with small primer plug, sleeve, and spring is built for reloaders who want a straightforward, reliable workhorse for precision ammunition assembly. This is a purpose-built reloading press designed to handle the repetitive, controlled movements needed to resize cases, seat bullets, and prime brass with consistency. The Rock Chucker Supreme gives you the control and repeatability that serious handloaders depend on, whether you're fine-tuning loads for competition, hunting, or high-volume shooting.

Single stage presses excel at accuracy and control—you complete one operation per stroke, which means you can focus on each step and catch mistakes before they become problems. The Rock Chucker Supreme's solid frame and mechanical advantage make it capable across a wide range of cartridge sizes. The inclusion of the small primer plug, sleeve, and spring means you're equipped to handle small primer cases right out of the box, saving you a separate purchase and setup time.

If you reload for common rifle or pistol cartridges using small primers, this press gives you the foundation to produce ammunition that matches your specifications. Paired with quality dies, a scale, and proper technique, the Rock Chucker Supreme will deliver the consistency that separates good handloads from great ones.

Frequently Asked Questions

What primer sizes does this press handle?

This press comes equipped with a small primer plug, sleeve, and spring, so it's ready to prime small primer cases. You would need to purchase a separate large primer plug and sleeve if you also reload large primer cartridges.

Is the Rock Chucker Supreme suitable for a beginner reloader?

Yes. Single stage presses like the Rock Chucker Supreme are often recommended for new reloaders because they encourage careful, deliberate work and make it easy to spot setup issues before they affect multiple rounds.

What reloading dies are compatible with this press?

The Rock Chucker Supreme accepts standard reloading dies. Your choice of dies depends on the cartridge you're reloading for and the type of reloading (full-length sizing, neck sizing, etc.)—not on the press itself.

What comes in the box?

This package includes the Rock Chucker Supreme press, a small primer plug, a small primer sleeve, and a spring. You will need to source a reloading die set, shell holder, and other components separately.
