I have seen quite a few posts concerning shooting high or low, to the left or right. Of course one of the first things to look at is how you're sighting the target. I believe another primary concern is finger placement and trigger pull. Some believe that the index finger pad is the best position and I tend to disagree. I have found that the separating line between the first and second pads ( I guess it's called the power crease by some and the distal joint of the finger on the palmar side by professionals) gives a straighter more even pull, especially on longer pull firearms. Give it a try and see what you think. Any other points or suggestions to help?
