Are you right handed? If you are; you might be dealing with the problem of clamping down just before the shot goes off.
Stick your empty hand out in front of you in the shooting position, then tighten (forcefully) your 3 bottom fingers into your palm and watch where your index finger goes... It drops down and left. The best thing to do is to buy some Snap-Caps. Have a buddy load your magazine for you, dropping a Snap-Cap or two into the mix randomly.
Watch your muzzle direction on EVERY shot. When you come up on a dud... You'll see exactly what occured. Even better, have your buddy film your shots from over your shoulder.
