Hornady Lock-N-Load Cartridge Gauge 6mm Creedmoor - Silver

The Hornady Lock-N-Load Cartridge Gauge is a precision reloading tool purpose-built to confirm that your brass and loaded ammunition will drop freely into a SAAMI-spec chamber. Sized specifically for the 6mm Creedmoor (.243 bullet diameter) cartridge, it is machined from steel with a silver finish and lets the reloader verify headspace and dimensional correctness without ever putting a live round through a rifle.

Simply insert a resized case or a finished round into the gauge - if it seats fully, the case or ammo is within SAAMI chamber tolerance. If it will not drop in, you will instantly know the shoulder is bumped too far forward, the case length is over spec, or the round is otherwise out of dimension. It is an essential bench tool for any 6mm Creedmoor handloader chasing consistent accuracy and safe case fit.
