Where can I get a Weatherby headspace/bump gauge???

[JDB]

I've got a 257 weatherby and I want to get a gauge to dial in my sizing shoulder bump.....I cannot find one any where? Any ideas?

Need this but for 257 wby or some other wby double radius neck:

.400 should work.

It would be either a C-.375 or a D-.400. You could probably use either. The cross section they have listed for saami is .3963 which is in between both of C&D.

Awesome, thanks guys. I ordered the .400 gauge and it worked perfectly. Come to find out I was bumping my brass .012 which was leading to case separation at around 5x firing on the brass. Because of this handy little gauge I am able to dial in a .0015 bump -- thanks again for the help!
