Headspace Gauge Interchangeability

Many headspace gauges, particularly those in the rimmed or belted calibers, are interchangeable. If you order gauges for a 375 Winchester, we will send you a 30-30 WCF gauge and note on the invoice that the 375 Winchester uses 30-30 gauges. Belted cartridges having a .535" belt (example 7MM Rem Mag, 300 Win Mag, 300 Wby) generally use gauges having common dimensions. If you order gauges for one of these calibers, the invoice will read ... "uses std. Belted gauges."

For your reference, we offer this headspace gauge interchangeability list for our standard calibers. Those standard calibers not given here have their own unique gauges and are not interchangeable with other calibers. (Ask for a free adhesive-backed chart for your tool box with your next order.)
