I seem to have a tendency to open groups up always the same way - the shots that i blow are off to the left, about 3/4 in. Elevation is OK. I can't figure out what is happening. My trigger is set to about 1 lb. I place the pad of my index finger on the trigger. I wonder if this is not causing me to "push" the rifle to the left? Would I be better off squeezing with the very tip of the finger rather than the pad? How do you guys and gals do it?
