my arrows seem to corkscrew. they seem to shoot well and broad headsshoot in the same place. what is this telling me?

You probably have some sort clearance issue. What arrow rest are you using?

I'm using a limbdriver. I have sprayed it with powder and it doesnt show any signs of hitting.also it seems to be irratic(sp) and not always the same arrow. some times worse than others

Are you using good quality arrows, properly fletched? Have you tried paper tuning the bow?

I'm using realtree mfx 400 with 2 in blazers 100 gr field tips.bow tech gaurdian @65 lbs.28in draw length, shaft [email protected] did the fletching with a slight off set.do you think that moving the fletching one way or another would make any difference?or is this not the right set up?

Could the fletching be possibly contacting the cables?

I would check your nock alignment and then fletching alignment/general arrow construciton.
