What causes laterial left and right impacts. Working up a 6.5 creed load. I started to see a trend. My impacts are dead on with elevation but there is a left and right shift by several inches. This is going to be a hunting load with 100g and 127g TTSX. First started on a lead sled. then moved to chair and shooting sticks. Noticed over an inch differance bewteen the two in elevation. That it is think is recoil managment. Not going to shoot a deer with a lead sled. So was practiceing and working up load on chair and sticks. Noticeing hugh shift back and forth left and right in impact. elevation is allways less than 1/2". SO I think it is me...
