I picked up a PSE Viper (cheap), cause I had shoulder surgery recently and can't use my recurve. But I had to back off the limb screws some to even pull the damn thing back to cock it. Now I have done this to many bows and am fairly accurate when backing off limb screws, but ever since doing this, the flight of the bolts have been "unpredictable". I mean not hitting TWO targets stacked at 10 yards some times! Then the next one might hit right where it's supposed to.
I am unfamiliar with cross bows, have I created this problem by lowering the pull weight of the limbs? Or could this bow just be a P.O.S.?
Think that's a no-no. I'd tighten em back up. I set up a PSE for a guy and other than the D-A-R his had which was a pos like the Horton's have, it shot very well, tennis ball groups at 30 yds.
Are you using a rope cocker? Sounds like you may not be centering the string, if that's not it try different arrows. Once you get it dialed in w/ field points, then try bheads. sometimes when you go to bheads, the fun starts all over again, lol.
Edited to add: The rope cocker you appear not to be using also cuts the effort to cock in half, btw. If you keep hand cocking, mark the string at rest on each side of the rail w/ white out.
