Against better judgement I hit the range today. It was bitterly cold with the wind chill and I knew my shooting would suffer but I had to go....
So I took some of the advice from this thread and concentrated on consistent cheek weld positioning. I was able to measure using my fingers tucked tight and flat together ( like they would in a mitt) from a spot on my stock to my cheek and strangely enough this put a sight window in my scope to the point just after the vignette disappeared (hopefully a point of little to no parallax).
Shot 2 different loads and was able to get this effect.....looks like I was able to eliminate the 2 shot grouping...but I will keep trying to maintain it. Also only loaded up 4 of each load as I was seeing the difference in brand of primers with same load.
