The Hornady A280AI Lock-N-Load Modified Case enables precision handloaders to achieve optimal bullet seating depth for 280 Ackley Improved cartridges. This modified case works exclusively with Hornady's Lock-N-Load Overall Length Gauge to measure exact chamber dimensions and establish proper cartridge overall length.
What Makes This Different
Unlike generic modified cases, this Hornady piece features precise chamber specifications that match SAAMI standards for the 280 Ackley Improved cartridge. The case body maintains exact headspace dimensions while the modified neck allows the Lock-N-Load gauge's bullet comparator to function properly. Standard measuring tools cannot provide the chamber-specific data this system delivers for optimal accuracy.
Key Features
- Precision-machined for exact 280 Ackley Improved chamber specifications
- Compatible exclusively with Hornady Lock-N-Load Overall Length Gauge
- Modified case neck allows proper bullet seating depth measurement
- Maintains SAAMI headspace dimensions for accurate readings
- Enables measurement of specific rifle chamber variations
- Works with all bullet weights and profiles in 280 AI
- Reusable design for multiple measurement sessions
Handloaders achieve consistent accuracy by determining the exact distance from case head to bullet ogive contact point in their specific rifle chamber. This measurement eliminates guesswork in seating depth selection and helps establish optimal jump distances for different bullet types. Competition shooters and precision hunters rely on this data to develop loads that maximize their rifle's accuracy potential across various bullet weights and designs.
