Headspace gauge for 30-378?

[seidersjoden]

Who makes a headspace gauge for 30-378, does hornady make one that works, they don't list it for the caliber?

Thanks

The 30-378 is a belted The head space is done off the belt. If you want a gauge to check the seating depth
Find someone who will make one off your fired case. Many in here can do that for you. Larry

What exactly are you looking for? A headspace gauge (go gauge)? Or a comparator to measure shoulder bump on sized brass?

I'm looking for a comparator to manage a shoulder bump.

I already have hornadys seating depth gauge.

Innovative technologies digital headspace gage, will work excellent. Better then most other tools for this anyway.
Works with calibers from 22 Hornet to 378 WBY, and is far easier to use and get consistent results from then the caliper attachment versions from Sinclair, Hornady, bump collars an so on.
Very satisfied with mine.

Shooting the case you do, you most likely want to look into his collet die for belted cases too.

Oh, a bump gauge!

Find a reamer print and find out what diameter the shoulder datum point is and either buy an insert from Hornady or have someone make you one out of aluminum. It is very easy to make.
