HORNADY A220 220 SWIFT MODIFIED CASE

Hornady Lock-N-Load 220 Swift Modified Case (A220) is a specially prepared brass 220 Swift case designed to thread onto the Hornady Lock-N-Load O.A.L. Gauge so you can measure true chamber-specific bullet seating depth and jump to the rifling. This Hornady A220 modified case uses a threaded case head and a slightly oversized neck to hold the same bullets you intend to load, giving accurate, repeatable measurements in 220 Swift rifles.

Key Features

• Manufacturer part number: A220
• Cartridge: 220 Swift
• Case material: Brass
• Head modification: Case head drilled and threaded with a fine thread to attach directly to the Lock-N-Load O.A.L. Gauge
• Neck specification: Approximately .002 inch oversized neck to lightly grip bullets by tension
• Intended use: Overall length and seating depth measurement with Hornady Lock-N-Load O.A.L. Gauges
• Compatibility: Works with both straight and curved Lock-N-Load O.A.L. Gauges

Special Features

• Threaded case head ensures a secure, coaxial connection between the modified case and the O.A.L. Gauge, which helps maintain alignment in the chamber.
• Oversized neck allows you to insert and adjust the actual bullet you plan to load, instead of a generic probe, for true-to-rifle seating depth readings.
• Manufactured to SAAMI 220 Swift dimensions so the case fits properly in standard 220 Swift chambers while you measure.
• Purpose-built design avoids damage to your regular brass and simplifies the process of finding lands contact and preferred bullet jump for your rifle.

Practical Benefits

• The Hornady Lock-N-Load 220 Swift Modified Case (A220) fits precision-minded 220 Swift reloaders who want to tune bullet seating depth and jump to the rifling for accuracy.
• Using this modified case with the O.A.L. Gauge helps you determine the exact base-to-ogive length where your chosen bullet contacts the lands in your specific chamber.
• Once you have that measurement, you can set dies and seating stems to run consistent, optimized loads for varmint, target, or hunting use in your 220 Swift rifle.
• If 220 Swift is part of your precision or varmint lineup, the Hornady A220 modified case is a practical addition to your setup for dialing in seating depth correctly.
