A longer barrel will give you a little more FPS to buck the wind at long range. You will still need the load work up for accuracy which may not be best at a higher velocity. Longer barrel, higher velocity does not mean more accuracy.I just bought one a few days ago and have fired 65 rounds through the stock barrel. So far I am considering a few upgrades, first of which is a 26" heavy barrel. The 20" barrel is ok, but I think I might get a little better accuracy if I switch to a longer barrel.
Any thoughts from those more experienced with this?
