The Hornady PTX Powder Measure Stop With Top And Bottom Adjustment Screws (Model 290049) is a mechanical reloading accessory designed for the Hornady Case Activated Powder Drop (CAPD, Item #050073). Constructed from machined steel, this bracket assembly attaches directly to modern CAPD units featuring a vertical return spring. It allows handloaders using Hornady Powder-Through Expanders (PTX™) to adjust case mouth flare and measure stroke limits independently of the powder die height, eliminating the need for a standalone case mouth expansion die on progressive presses.

Key Features

• Dual-Screw Adjustment: Features knurled, threaded top and bottom adjustment screws with locking nuts to independently fine-tune the powder measure stroke limit and the exact depth of the case mouth bell.
• Multi-Stage Station Efficiency: Integrates the case flaring step directly into the powder drop station, freeing up an additional station on progressive presses for accessories such as a powder checker or a dedicated taper crimp die.
• Machined Steel Construction: Built from durable steel components designed to maintain consistent flaring settings across high-volume reloading sessions without shifting.
• Fully Mechanical Operation: Requires no electrical power, batteries, or external power connections to operate.

Who is the Hornady PTX Powder Measure Stop With Top And Bottom Adjustment Screws for?

• High-volume handgun reloaders using Hornady Lock-N-Load AP progressive presses — integrates case mouth flaring into the Item #050073 powder drop assembly weighing under 100 g, freeing up an essential press station for auxiliary check dies.
• Competitive shooters reloading straight-walled cartridges like 9mm and .45 ACP — allows direct mechanical adjustment of case mouth bell depth on Item #050073 drops via independent steel adjustment screws without altering primary die height.

Less suitable for: Reloaders processing bottleneck rifle cartridges like .223 Rem or .308 Win that expand during neck sizing rather than at the powder drop, who require standard full-length sizing dies; or owners of legacy Hornady CAPD units utilising a 4-inch diagonal return spring, who require older-generation replacement brackets or complete modern powder drop upgrades.
