    @R93 - the cold bore first shot velocity difference and clean bore vs fouled bore velocity difference is a common phenomenon. The long-range target stuff that I do is out to 900yds - you get two 'sighters', then (normally) 10 counting shots. The first shot of the day is pretty much always lower vertically, usually more so for a clean bore, due to that velocity difference.
    My F class rifles clean cold bore shots are 1 MOA low for my first sighter I add ! MOA elevation and take it off for the second if your wind call is correct you get 2 keepers very handy in the F disciplines.
