HORNADY A22250 22-250 REM LOCK-N-LOAD MODIFIED CASE

Hornady Lock-N-Load 22-250 Remington Modified Case (A22250) is a specially prepared 22-250 Rem brass case designed to thread onto Hornady Lock-N-Load O.A.L. Gauges so you can measure true chamber-specific bullet seating depth and jump to the rifling. This Hornady A22250 modified case uses a threaded case head and a slightly oversized neck to hold your actual 22 caliber bullets, giving accurate, repeatable measurements in 22-250 Rem rifles.

Key Features

• Manufacturer part number: A22250
• Cartridge: 22-250 Remington
• Case material: Brass, manufactured to SAAMI 22-250 specs
• Head modification: Case head drilled and cut with a fine thread to attach directly to Lock-N-Load O.A.L. Gauges
• Neck specification: Approximately .002 inch oversized neck to lightly grip standard .224 bullets
• Intended use: Seating depth and overall length measurement with Hornady Lock-N-Load O.A.L. Gauges (straight model C1000 or curved model C1550)
• Package: One modified case per package

Special Features

• Threaded case head creates a solid, coaxial connection between the modified case and O.A.L. Gauge so the assembly stays aligned when you insert it into the chamber.
• Oversized neck holds the same bullets you plan to load, instead of a dummy probe, which produces true-to-chamber measurements for that bullet profile.
• SAAMI-spec base and body geometry ensure the modified case fits standard 22-250 chambers correctly while you determine bullet-to-lands contact.
• Purpose-built design keeps your regular brass out of the modification process while giving you a dedicated test case for repeatable measurements.

Practical Benefits

• The Hornady Lock-N-Load 22-250 Remington Modified Case (A22250) fits 22-250 shooters who want to tune bullet seating depth and jump for improved accuracy in varmint, target, or hunting rifles.
• Using this modified case with an O.A.L. Gauge helps you find the exact base-to-ogive length where your chosen bullet touches the lands in your specific barrel, then back off to your preferred jump.
• Once you record that dimension, you can set seating dies and comparator tools to produce consistent, optimized loads for your 22-250 without repeated trial and error.
• If 22-250 Rem is one of your main varmint or precision cartridges, the Hornady A22250 modified case is a practical tool to add to your measuring kit so you can dial in seating depth correctly for each bullet you run.
