Re: A miss. Now what?
Double check the scope dope or that you used the correct hold over. If there is a descrepancy, fix it and fire a follow up shot. If there is no descrepancy, I would attribute it to the "cold bore shot" and fire a second shot from a warm barrel. If that doest connect, I would go to the range and figure out if it was me or the rifle. Of course only after I was SURE i didnt connect and leave a wounded critter in the woods. I have taken shots in such cold weather from such a cold barrel that I was pretty sure the first shot would NOT connect. Guess what, they didnt. The second ones sure did! I was also positive the situation would allow for a secong shot in case a less than perfect shot occured.
Long range shooting is a process that ends with a result. Once you start to focus on the result (how bad your last shot was, how big the group is going to be, what your buck will score, what your match score is, what place you are in...) then you loose the capacity to focus on the process.
