Drill and tap revolver for scope mount?

[trlcavscout]

I need to get a hunting revolver filled and tapped for a scope mount, anyone have someone they have used and recommend? Up north would be awesome but I might make a drive. I am looking at cost VS using a no drill Weigand for $130 which is a great mount just big and bulky.

What's the revolver and what's the thread size you need?

I run a machine shop between Longmont and Boulder.
