The Rock Chucker Supreme Auto Prime unit converts one-at-a-time priming to a tube-fed priming system and eliminates the handling of primers.
It attaches to the same place as the standard priming arm.
Attach the proper primer cup and seat plug to the priming arm slide, insert the correct primer tube and safety shield, fill the primer tube, and a reloader is ready to prime.
The straight push-pull primer arm slide reduces the chances of primers falling out of the primer seat plug.
