The one shot I really worry about is first shot from a cold barrel. I need to know exactly where it is going to hit in relation to my crosshairs. Groups show consistent loads and they are fun on paper but that first shot needs to be, for example, 2" higher than the point of aim at 100 yards from a cold, fouled barrel every time to be of interest to me. When the crosshairs are in the right place, I want to know where that first bullet is going to hit. That is what makes or breaks a season of hard hunting and preparation.
