Testing shows 455 is optimal for non ported cylinder at about 400-450 fps. This is assuming you have top quality barrel and r hop and planning to build a dmr/sniper rifle. Otherwise Hectic is pretty much correct since the accuracy difference is minimal and a cheaper longer barrel will make things worse.
