I zero'd my gun at 50 meters they other day,then fired 4 shot's to see where the bullet was hitting,I fired the first one at 25mtrs, second at 50mtrs, third at 75mtrs,and the last one at 100mtrs,I had a slight wind coming from my left but didn't allow for it I just put the crosshair's on the half inch bull,the point of impact was allmost the same the picture of the target shows how flat shooting the HMR is I was re-zeroing because I changed my scope from a 6x24x50 to a 6x24x40 as the 6x24x40 sit's lower to the barrel my sight height is 1 1/2 inches I was using 20gr pills.Hope this helps.
