Just taking a survey, for discussion, not looking for a solution. What is your prefered trigger pull weight for offhand rifle shooting? I will tell what I learned, and what works for me. All my shooting, except load testing and zeroing, are done offhand. My shooting is cast bullets only. I re barreled several rifles, and put aftermarket triggers in them. I always requested the lightest weight they offered, usually 1-1.5 lbs, thinking I would shoot better with the light trigger. Boy was I wrong.
I found myself having the usual wobble area, varying from day to day, dependent on how my aging body felt, and how much caffeine I ingested. The rifle would not settle down. With my finger barely touching the trigger, out of desperation, I found myself slapping the trigger as the crosshairs drug across the target, which was usually a steel gong. I missed the gong an awful lot.
I then tried something counter intuitive, increasing the the trigger pull, and my shooting improved greatly. I could then rest my finger, with some pressure on the trigger. This pressure, however light, actually made the rifle hold steadier, and the break of the heavier trigger, was more of a surprise, allowing much better hits. Trigger pulls in ounces, are great for bench shooting, but for offhand shooting, 2.5 to 3 lbs, is now the desired weight for me. Heavier triggers are no longer bad, as long as they have a clean break.
