OK bonny, here is my 2cents worth. I think V thread would be ok, but if you don't like them, use acme thread. The internal thread is the concern. You would cut the acme thread with the compound set to 14 degrees, cutting mostly on one side of the tool, but the square thread has to be plunge cut. Of course both would have to be cut using a boreing bar, but the square thread is more critical and flex in the bar will give more problems. On the other hand, it is your project, you can do whatever you want.

Mike, many thanks for taking the time to reply. What it is, is i have a westley richards 1897 type action with v-threads already cut. But looking at the action with its flat front surface, i was thinking it would be relatively easy to barrel the rifle as a take-down. But i would worry about the wear on the threads.
