Gauges are interchangeable on many cartridges. All the Creedmoor family cartridges use the "parent" case gauge, 22,6mm,25 & 6.5 CM all use the same gauge. .308 gauges work on, .243 Win, 260 Rem, 7mm-08 Rem. and .338 Federal. 30-06 gauges work on 25-06 Rem, 6.5-06 Rem, 270 Win, and 35 Whelen etc. Same for the Winchester Short Magnum family, Remington Short Action Ultra Magnum family and so on.
Headspace gauge interchangeability is common and gauges are commonly labeled with the "parent" cartridge, although some gauges may have multiple cartridges marked on the gauge.
