Speaking of 50's...the Govt Round

[Mike]

Kurt, I asked John Taylor if he could do that and he says "yes!" However, he might argue in favor of a .504/.510" combination.
You can contact him at info@johntaylormachine.com. And Joe Williams should be able to do that too. I've been thinking about getting a .50 caliber 1 turn in 32" myself to build up a .50/70 Rolling Block. Shoot sharp, Mike
