I am currently in the process of building a .30-06 for target shooting and possibly competition out to 1,000 yards and for occasional hunting. So after doing some searching online it seems the most common is 1/10" twist. Which should stabilize heavier bullets well. 1/12" seems like it would stabilize lighter bullets well and 1/11" seems like it might strike a good middle ground. From what I read the 1/10" twist was originally put on the .30-06 for a 220 grain bullet but because it still shot well with other bullets it was kept. So any opinions on barrel twist for accuracy on this old round?
