The Hornady Lock-N-Load Modified Case for .204 Ruger is a purpose-made reloading tool designed for use with the Hornady Lock-N-Load O.A.L. Gauge. A modified case is a standard cartridge case that has been drilled and tapped to accept the O.A.L. Gauge's bullet-holding assembly; it fits into your rifle's chamber just as a live round would, allowing you to measure the precise distance from the bolt face to the lands — the true cartridge overall length for that individual barrel. This information is essential when dialling in seating depth for accuracy work, as it lets you set a specific amount of jump or allow the bullet to engage the rifling. Hornady manufactures this case to SAAMI specifications, ensuring it fits .204 Ruger chambers correctly without requiring forcing or over-travel. The result is a reliable, repeatable datum from which to develop loads, particularly useful for the flat-shooting .204 Ruger chambering favoured by fox and varmint shooters seeking tight groups at long range.
