The Hornady Lock-N-Load A Series Modified Cases in 7.62x39mm (A762) are precision reloading tools designed for shooters who demand accuracy in measuring cartridge overall length. These specially prepared cases work exclusively with Hornady's Lock-N-Load Precision gauges and O.A.L. measurement systems. Whether you're developing handloads for an AK-pattern rifle, setting up your AR platform in 7.62x39, or fine-tuning ammunition for a bolt gun, these modified cases let you verify bullet seating depth with the same exact bullets you'll be loading—eliminating variables and ensuring repeatable results to within .001 inch.
The engineering here matters. Each modified case has a fine-threaded case-head that attaches securely to your Lock-N-Load gauge, holding the case perfectly square and centered for precise chamber alignment checks. The case neck is precision-rounded and opened slightly—oversized by .002 inch—so a standard-diameter bullet seats concentrically without forcing or binding. That concentricity is critical; sloppy fit in a measurement tool defeats the purpose entirely. Because you're using the actual bullets you intend to load, your O.A.L. reading translates directly to your cartridge specifications without guesswork.
These cases are manufactured to SAAMI specifications and thread-attach to either generation of Hornady O.A.L. gauge, giving you flexibility as your reloading setup evolves. If you're serious about consistency and your loads demand precision measurement, the Lock-N-Load system paired with caliber-specific modified cases is a proven way to cut variables and improve reliability.
| Cartridge | 7.62x39mm |

Yes. The fine-threaded case-head design works with either generation of Hornady's O.A.L. gauge system, and the case threads securely to ensure precise, repeatable measurements.
The case is designed to work with standard-diameter bullets matching the caliber you intend to load. For the most accurate O.A.L. readings, use the exact bullets you'll be seating in your finished ammunition.
You receive the modified case only. A dial caliper and O.A.L. gauge are sold separately and are required to perform measurements.
No. These modified cases are precision measuring tools only and are not intended for reloading. They're used exclusively with Lock-N-Load gauges to verify overall length specifications before you load your cartridges.
