Case/bump guage for 338 Lapua Improved?

[Despotes]

I'm in the process of getting reloading equipment ordered for my build, but can't find anything I can use for a case gage for the Lapua Improved.
Any ideas?

Easy. Tell your smith to make a stub guage out a scrap I
piece of barrel using the chamber reamer. Normally costs $25-40 depending on the smith

Good article on 6br daily bulletin this week on the stub guage.
