The Lee Automatic Case Primer (ACP) Bench Priming Tool is the world’s first automatically case fed, shell holder less priming tool. Metallic cartridge priming was revolutionized in 1979 with Richard Lee’s patented Auto Prime tool. Today most all handheld priming tools share most if not all the features of the Original Auto-Prime. The ACP truly automates priming. Think of it as the “Real” AUTO-prime. No shell holders required, cases are guided into position by the “finger guide”, priming is positive, effortless and uniform. Positive and consistent seating depth is assured with the dead length priming device. Primers are seated uniformly without “feel” or adjustments required. Seating is almost effortless as the priming tool shares the powerful linkage of Lee Automatic processing presses. The best feature is the ability to automatically feed cases!

Will seat large and small rifle and pistol primers. Automatically feeds and primes cases up to 2 ½ inches long.
