Looking to buy a CMM4 tomorrow at the CLA. I want to use it on both my deer rifles. My .243 is already cut with 1/2 UNF thread.
It has been surgested cutting a 1/2 UNF thread on a Tikka T3 lite .30-06 barrel is not ideal as it does not leave much material (Thickness) between the end of the thread and the bore.
What I want to know is, is it an absolute no go or is it just not ideal?
I dont want to buy the mod tomorrow and be told by the riflesmith he is not happy cutting with a 1/2 UNF thread!
Thoughts please gents. Thanks in advance.
