Douglas barrel groove depth?
« on: October 29, 2015, 06:18:18 AM »
Anybody know what depth rifling Douglas was using back in the 70s on 40 cal barrels?

I have a couple of Douglas .40s from the early 80s with 1/66 twists. Groove to groove measurement is. .424" so rifling is .012".  I do not know if they used a different depth in their 1/48 twist barrels.  Why not call Douglas in West Virginia and ask them?

Nothing is hard if you have the right equipment and know how to use it.  OR have friends who have both.
