Hornady Lnl Modified A Cases - .220 Swift

The Hornady LnL Modified A Cases in .220 Swift are precision-engineered cartridge cases designed for reloaders and competitive shooters who demand consistency and accuracy. Built specifically for use with Hornady's Lock-N-Load Precision gauges, these cases serve a critical function in the reloading process—ensuring that every round is dimensionally verified and perfectly aligned before ammunition assembly. Whether you're a precision rifle competitor, long-range hunter, or serious handloader, these modified cases eliminate guesswork from the case inspection phase.

The .220 Swift cases feature a fine-thread attachment system that screws directly onto Hornady's Lock-N-Load gauges, guaranteeing perfect square positioning and chamber alignment every time. This threaded interface prevents cocking or tilting—a common source of measurement error in manual reloading. The modified design allows you to measure critical case dimensions (headspace, neck tension, overall length) with repeatable precision, which directly translates to tighter velocity spreads and more consistent bullet groupings downrange. For the .220 Swift cartridge, known for its flat trajectory and varmint-hunting effectiveness, this level of dimensional control is essential for maintaining sub-MOA accuracy.

Reloaders working with .220 Swift rifles benefit most from these gauge cases, particularly those using Hornady's complete LnL Precision reloading system. Compatibility is seamless with all standard Hornady Lock-N-Load headspace and chamber gauges designed for the .220 Swift caliber. The lightweight, compact design (0.04 lbs) makes them easy to store and handle during extended reloading sessions, and the fine threads resist stripping with repeated use. If you're building match-grade ammunition or conducting ammunition development, these modified cases are an essential quality-control tool.
