I had (still probably have it a little to be honest!!) similar, a stringing assist says the palm of right hand is pushing the stock down and left at/after the trigger pull.
Plus for me either a) leaning into the rifle a bit too much can cause the muzzle to tip up at the shot,
b) not being square (in this case your body being a bit left and leaning right into the rifle) behind the rifle. I was setting up with body just a bit left and unconsciously leaned to the right - webtalk says the way you're leaning makes the shot go that way as well. Makes some sense to me b/c there's a sharp force and break at the shot which could cause a slightly-off-balance body to re-position slightly... 1/1000's of an inch at the shot multiplies into 1/10's or bigger at the target.
o, and disclaimer... I'm not an expert, there are several on here who are. I'm just sharing what seems to help for me.
