agr516Measuring Weatherby Headspace
What are some of the tools/methods you all use to measure the headspacing of Weatherby cartridges? I use RCBS Precision Mics with my standard cartridges but am not sure where to begin with the Weatherby double radius.
If it is a belted magnum Weatherby the headspace is on the belt. What caliber are you using?

agr516I am hoping to find a way to measure the headspace using the case shoulder. I'm not sure I trust the idea of indexing headspace from the belt. The caliber is 300 Weatherby.
As 30-378 says you are not measuring headspace but "head clearance" when you measure the gap on new cases between the case shoulder and chamber shoulder.
Saying that, I use the regular
Hornady Headspace Gauge. It will work on a radiused shoulder just like a sloped shoulder.
