Best conditions to establish aim points / clicks on a scope
I've been going through the motions of setting up my new Sightron SIII scope and one I've found is it ranges very well in all temperatures & light conditions (so far) so I'm really happy there.
I've been setting up & establishing my click chart and had them pretty well set and this was carried out outside in about 12 degree temperature and modest light. Tonight I went to Pete's indoor range as I had spare time and thought I'd double check everything indoors but everything was quite a few clicks out and at 50 yards there was no consistency in shot placement, it went off at about 40 yards.
Is it pretty normal that the cold (it was about 1 degree outside) can affect point of impact and this is where you have to "learn your scope" or being new to this am I missing something that could help me?
