OK, after calling around to a few barrel manufacturers, finding a chrome moly barrel, #5-ish contour in a 1:9 twist or faster will require it to be custom made with a 4-6 month lead time. CM is the limiting factor
Krieger has the above in stock, but it's a 1:10
Would I be leaving too many bullet choices and too much performance on the table if I bought the 1:10?
I could go stainless but then I'd give up the bluing. Since this would be a nicely finished wood stocked hunting rifle and FN Mauser action, I kinda had my heart set on having the metal blued.
Pick the bullet you plan on using, plug in the worst case scenario environmental variables into the Berger twist rate calculator and see what you get.
