The following is a partial listing of those cartridges which use the same Belted Magnum Headspace Gauges: .257 Weatherby Mag., 6.5 Rem. Mag., .264 Win. Mag., .270 Weatherby Mag., 7mm Rem. Mag., 7mm Weatherby Mag., 7mm STW, .300 H&H Mag., .300 Weatherby Mag., .300 Win. Mag., .30-.338 Win. Mag., .308 Norma Mag., 8mm Rem., .338 Win. Mag., .340 Weatherby Mag., .350 Rem. Mag., .358 Norma Mag., .375 H&H Mag., .416 Rem. Mag., .458 Win. Mag.MIXING AND MATCHING BRANDS OF HEADSPACE GAUGES - Don't do it!! That's the short answer, here's why. It boils down to tolerance stacking. Each Headspace Gauge manufacturer works within a range specified by SAAMI. Manufacturer "A" may work at the high end of the range while Manufacturer "B's" gauges are in the middle of the tolerance range. Mixing the two could give an inaccurate reading. By sticking with one brand within a particular caliber, you will eliminate a variable. If you have a Forster, .308 GO gauge, get a Forster, .308 NO GO. Use Clymer with Clymer and Manson Precision with Manson Precision, etc. You can use any brand of headspace gauge with any other brand of chambering reamer. e.g. Forster Headspace Gauges with Clymer Reamers, Manson Precision Gauges with JGS Reamers, etc.Delivery time approx. 7-14 days.
The Belted Magnum Cartridge Headspace Gauges by Manson Precision are essential tools for determining the correct headspace for a variety of belted magnum cartridges. Designed for accuracy and reliability, these gauges are a must-have for any serious gunsmith or firearm enthusiast.
MIXING AND MATCHING BRANDS OF HEADSPACE GAUGES - Don't do it!! Using gauges from different manufacturers can lead to inaccurate readings due to tolerance variations. It is recommended to use the same brand for both GO and NO GO gauges within a particular caliber. For example, if you have a Forster .308 GO gauge, pair it with a Forster .308 NO GO gauge. Maintain consistency by using Clymer with Clymer and Manson Precision with Manson Precision.
Utilise any brand of headspace gauge with any other brand of chambering reamer, such as Forster Headspace Gauges with Clymer Reamers or Manson Precision Gauges with JGS Reamers.
