The Hornady Lock-N-Load Modified Case in 6.5 PRC (Hornady part no. B65P) is a precision gauge accessory, not a live case. A fine thread locks it square onto Hornady’s Lock-N-Load Precision gauge, while the resized case neck lets a standard-diameter bullet slip in concentrically for a true reading. Handloaders use it to measure exact bullet seating depth against their own rifle’s throat instead of guessing from a load manual, which matters most for precision rifle and competition shooters chasing tight seating-depth tolerances. Find it in our reloading equipment lineup alongside the rest of Hornady’s measuring tools.

Key Specifications

• Ships at a listed weight of about 0.8 oz, light enough to add to any gauge or die order.
• Built for 6.5 PRC brass.
• Fine-thread attachment point locks the case perfectly square onto the Lock-N-Load Precision gauge.
• Neck is resized round and opened slightly so a standard-diameter bullet slips in concentrically, without binding.
• Delivers precise, repeatable alignment in your own rifle’s chamber for accurate seating-depth measurements.
• Pairs with the Hornady Lock-N-Load Precision gauge system — sold separately.
• Classified by Hornady as a Modified Case, a dedicated gauge accessory rather than a fireable case.
• Made from real brass, not a synthetic dummy round.
• Not loaded ammunition — an inert measuring accessory with no powder or primer, so it ships and stores like any other reloading tool.
