The Hornady Cartridge Gauge for 7mm-08 Remington (Hornady part no. 380712) is part of Hornady’s Lock-N-Load Cartridge Gauge line, built to check that your cases and finished ammunition will fit correctly in a SAAMI-spec chamber. Sized to the .284-inch bullet and case diameter that defines 7mm-08 Remington, this single-caliber gauge gives a tighter, more precise fit check than a universal tool. Drop a case or a loaded round in; if it fits, it’s within SAAMI dimensions and ready to chamber. At well under a pound, it’s an easy addition to any reloading kit for handloaders who want to catch an oversized case before it ever reaches the range.
