The Lee Precision Ram Prime is a priming tool that allows reloaders to seat primers using their single-stage press. It works on the up-stroke of the press ram, utilizing the press's powerful leverage to seat primers with minimal effort while still providing excellent tactile feedback. This method gives the user a better feel for correct primer seating than complex press-mounted systems, without the hand fatigue that can come from handheld tools. The universal design works with nearly any standard single-stage press and standard shell holders, and the kit includes priming assemblies for both large and small primers.
