A tight bore barrel will keep the bb flying straighter, a longer TBB will keep it straighter longer. I have one gun that has a 6.01x300mm bbl that is shockingly accurate, however I have a gun with a whopping 6.08x620mm and even with the sloppier tolerances, the longer one has better accuracy at the same range and has about a 50 foot longer range.
Bottom line, get the barrel that fits your gun, unless you want to run a silencer, if you are, you might as well fill it with a longer inner barrel.
I DID NOT INVENT THE INTERNETS FOR THIS
