The Ram Priming Unit is built to improve primer seating control and overall reloading precision by positioning the seating action at the top of the press stroke. This design enhances feel and promotes uniform seating depth, while the ability to preset a positive stop streamlines operation and supports faster, repeatable performance. Compatible with any single-stage or turret press using 7/8-14 threads and an RCBS-type single-stage shell holder, the unit works with Boxer-type rifle and pistol primers and includes both large and small primer rod assemblies. Offering consistent function and broad versatility, it serves as an efficient and dependable upgrade for a wide range of reloading setups.
