Barrel Length for .270
Been going back and forth on the .270 and .308 for my next rifle. From what I have read around the net, it seems the .270 requires a longer barrel for peak performance, somewhere in the vicinity of 22" or longer, where as the 308 seems to prefer a shorter barrel (20" or shorter).
I know that barrel length equates to velocity, so my main concern is whether there are barrel length limitations to the .270
Is this correct?
