Marky,
Tried your trigger pinch technique along with repositioning my cheek rest closer to the end of the stock. This postion puts very little torque on the rifle in the rest. Was able to put 5 rounds in one hole at 50 yards, and in calm conditions, 3 in an inch group at 100. I feel comfortable with making 100 yards my starting zero at this point. Got a 455 in 17 HMR on the way. Ranger Point is putting a Boyd's stock on it for me with a trigger job to get the same tension as my 455 22lr. Maybe its old age, but I feel the kid before Christmas in Christmas Story. :-) Thanks for the tip. Mark
