Brux, Krieger, Muller barrel on either for the win, reamer with appropriate freebore dia and length for the bullet you want to shoot.
12 twist for 60g V max and lighter bullets
10 twist for 60g Sierra TMK
8T for up to 77g TMK
7T for 88g ELDM
Proper throat length and dia for each yields great dividends in barrel life and accuracy for each, and this is one issue you should not throw your brain away on. Some Hornady bullets are running .2245 for pressure ring dia and if you have a throat that is .2245(typical), you are in trouble.
Not everyone hunts/shoots in the windy plains states, nor do they shoot over 300 yards.
Remember, heavy bullets in 7-8 twists eat up bores in a hurry, 800 rounds.
