#5 Lock-n-load Ap Progressive Press Shellplate

The Hornady #5 Lock-n-load AP Progressive Press Shellplate is a precision reloading component engineered for serious handloaders and competitive shooters who demand consistency across magnum cartridge families. This shellplate is purpose-built for the Hornady AP (AutomatiC Progressive) reloading press, enabling rapid production of match-grade ammunition for large-bore rifle cartridges including .338 Winchester Magnum, .340 Weatherby Magnum, .350 Remington Magnum, .358 Norma Magnum, and .375 H&H Magnum. Field-tested by precision rifle competitors and professional reloaders, this component eliminates setup delays when switching between compatible magnum loads.

The Lock-n-load system features a quick-change design that securely indexes each cartridge family without trial-and-error adjustment, reducing operator error and ensuring repeatable press alignment shot after shot. Hornady's engineering eliminates runout variance caused by loose shellplate fitment—a critical factor in magnum cartridge reloading where case concentricity directly impacts velocity consistency and downrange accuracy. At 0.6 lbs, this shellplate integrates seamlessly into the progressive press station carousel, maintaining the system's balance and operational rhythm during high-volume production runs typical of long-range hunting or match preparation.

Operators transitioning between .338 Win Mag and other large magnum cases benefit from the #5 shellplate's compatibility across this cartridge family without requiring complete press recalibration. Law enforcement armorer shops, precision rifle builders, and civilian long-range competitors rely on dedicated shellplates to maintain production speed and accuracy standards. This component is essential for anyone standardizing a progressive press for multiple magnum calibers, eliminating the guesswork inherent in manual adjustment and delivering the repeatability that separates hand-loaded ammunition from factory loads.
