windage

[Philo]

Hi all
was down the local range and I've noticed that the zero has moved 3 to 4 clicks (windage ) a couple of times now the temperature has fallen ?
is it me or has anyone else had this problem.
ps it's an indoor 25m range

It is pretty normal. Temperature affects pressure and therefore - the POI.

I've put my rifle outside for a couple hours before shooting on cold days to let the gun and scope become acclimated to the temp. It really helps
