Lee Auto Prime Shell Holder #19

The Lee Auto Prime Shell Holder #19 is a dedicated priming tool designed specifically for Lee Precision's Auto Prime hand-priming system. Unlike universal shell holders designed for reloading presses, this shell holder works exclusively with the Auto Prime to deliver consistent, reliable priming of rifle and pistol brass during the hand-reloading process. Manufactured in the United States by Lee Precision, a manufacturer with decades of experience in the reloading industry, the Auto Prime Shell Holder #19 represents the precision engineering expected from this established brand.

The #19 holder accommodates .40 S&W, 9mm Luger, 10mm Auto, .38 Auto, .38 Special, and .41 Action Express cartridges. This multi-caliber compatibility eliminates the need for separate holders when working across common defensive and practice cartridges. The compact design—measuring 3.7 x 0.3 x 5 inches and weighing just 0.04 pounds—integrates seamlessly with the Auto Prime system, which itself is engineered for manual operation without a press. Proper shell holder sizing is critical to consistent priming: too loose, and the brass won't seat firmly during primer insertion; too tight, and case damage results. The #19 is engineered to hold these mid-sized handgun cartridges securely without marring.

Hand-priming systems appeal to reloaders who value workspace flexibility, control over primer seating depth, and the ability to feel precisely when a primer bottoms. Serious handloaders, competition shooters, and those who reload multiple calibers in quantity find the Auto Prime and matching shell holders to be cost-effective alternatives to press-mounted priming systems. Because this holder is caliber-specific (unlike universal holders), it ensures proper fit and consistent primer seating—essential for reliable ammunition.
