It took me a little time to figure this one out but here is what I was doing. I have a fitted stock and the gun fits me great when I keep my mouth shut!! I realized that when I miss I do some dumb ass grin that moves the point of impact because my cheek is not relaxed!!I have no idea how I got into this habit but most of the time I miss I realize my mouth and cheek are in that position. It is a hard habit to break. I can usually shoot 23 or better when I remember not to do this. Have any of you guys ever had a similar problem. On my last round today shooting 7/8 7.5 shot I was crushing the birds, and the misses I believe were caused by the change in my mouth and cheek because it throws of proper alignment.
