Finally got to the range. Fired the 150 grn Hornadys with 46 grns IMR 4895, CCI 34 primers. Was on target with the first shot (8" X 11.5"). Had to adjust 2 inches left. My first groups pretty bad 3-8 inches. Rifle shoots a lot better than me. Will try different loads and try to concentrate on my breathing and trigger squeezing in the months to come. Totally pleased with this rifle and lookforward to scouring this board for all of the advice and information about the M1. Thanks to Ed,Smellie and TDH for all your help.
