The Hornady Lock-N-Load Cartridge Gauge, 6.5mm Creedmoor (part number 380710), is a drop-in gauge that checks whether a fired case or a loaded round is within SAAMI chamber specification for 6.5mm Creedmoor before it ever reaches a rifle. Reloaders drop a sized case or finished cartridge into the gauge; if it seats flush, the round will chamber cleanly, and if it doesn’t, you’ve caught an oversized case or a seating problem before a range trip or a stuck case in the field.

Key Specifications

• 6.5mm Creedmoor-specific chamber gauge sized to this cartridge’s SAAMI chamber dimensions, not a universal fit.
• checks both fired brass and loaded ammunition so it works as a sizing-die check and a final QC step on finished rounds.
• drop-in, no-press design giving a pass/fail read by eye with no tools or setup required.
• catches over-length or over-sized rounds before the range helping avoid a stuck case or a failure to chamber in the field.
• silver-finished body for a durable, easy-to-read gauge that resists corrosion at the bench.
• ships at approximately 0.34 lb a compact gauge that adds minimal weight to a die box or range bag.
