    Nort hemisphere temp stability data always seems to look at the impact of extreme cold. Not so relevant for us if it’s below 0 F.

    What I have found that is of significance is temp stability in the 35-42 C range. Not unusual in summer to have ammo at this temp due to ambient temp, sun exposure, hot chambers when on the range or in the field.

    Some reloader powders in particular RL22 will produce variations up to an extra 150 fps in a .25/06, .270 loading.
    Obviously accuracy and precision depart the room.
