Just got my new bow (2013 Bengal Pro-Hammerhead strings, 29"dl, 44 lb draw, Fletcher finger release and peep) and I've noticed that the peep sight doesn't always line up at full draw. I've been nocking my arrow and then giving the peep a quick twist with my fingers which brings it back in line for next few arrows.
Is this normal with a newly inserted peep? Or is there some kind of peep training/tuning I should be doing?

thanks, Keith
