I am not sure which gunsmiths are members here but I have had rifles built by Jon Beanland
Beanland Rifles and Greg Young
Southern Precision Rifles and have nothing but high praise for both of these guys.
Greg has built me two rifles and Jon has built me one with another to be complete in April.
Since you are in the notion for a 22-250, I too am having one built and I'm going to have Robert Gradous
Gradous Rifles build me a 22-250
Also, I'm having Greg Tannel
Gre Tan Rifles build me a 20 Tac
I don't think you could go wrong with any of these men.
