The Manson Precision No Go Headspace Gauge is compatible with most belted magnum cartridges based on the .375 H&H Magnum case, excluding the .240 Weatherby Magnum.
It is important not to mix and match headspace gauges from different manufacturers to avoid tolerance stacking and ensure accurate readings.
Headspace gauges from any manufacturer can be used with chambering reamers from another brand without issue.
