If your gun itself, is not producing consistent shots (bursts of air) you will be all over the shop.
Check and clean teh Hyper2 reg and teh bolt setup...dont over lube it and use shocker lube...set teh gun up over teh chrono, set teh LPR etc, so it is consistent over teh chrono...that will induce accuracy, when combined with good paint and good barrel match....assuming you dont SUCK
