Hornady Lock-N-Load Cartridge Gauge 7mm PRC .284 Go/No-Go

The Hornady Lock-N-Load Cartridge Gauge is a precision Go/No-Go chamber gauge for the 7mm PRC cartridge. Machined from carbon steel to a tight +/-0.0001 inch tolerance, it lets the handloader confirm that brass and finished ammunition will seat cleanly in any SAAMI-spec 7mm PRC chamber before they ever reach the rifle. Sized to the cartridge's .284" bullet diameter, this gauge is an essential case and ammunition fit-check tool for any 7mm PRC reloading bench.
