Ive heard a lot of things, from a lot of different people, but there doesnt seem to be any real consistency in what the best diameter for an inner barrel to be is. Ive been told 6.01 is the way to go, and Ive also heard that 6.07 is the one thats best for snipers. What is true, and what do YOU use? I personally have a 6.01 and have about a 2 inch grouping at 110 feet (after which it declines rather rapidly).
And rather than just saying the the best diameter, a little explanation as to WHY would be nice
