I haven't searched to see if or when this has been discussed, but I was thinking 'bout how do guys sight in their guns? Do they use a sled, or bags or shooting sticks, offhand, a bench, off the truck, do you have a level on your scope, how do you hold the gun, how do you control your heartbeat to keep the crosshairs from moving, etc..... Me, I'm a bench and bag guy(mostly) and try to hold the gun tight to my shoulder and use my off hand to just steady the fore end on the bag. I don't squeeze it tight, just enough to keep it from wiggling. I don't have a level on my scope either. I usually breathe in and then let out and squeeze the trigger at the end when my heartbeat has ended and the crosshairs are on the bullseye.
