Maybe someone here knows if really cold temps affect the ballistic performance of shot shells
Yes it does and I mentioned that above in my earlier post. Not only does cold air and especially cold dense air at this time of year affect velocity, it also negatively affects patterns as the cold dense air acts like an air brake. So it would only seem logical to shoot a tighter choke late in the year to attain the same pattern percentages that you once had in Sept/Oct with a more open choke. One only has to do his home work if curious and spend a little time at the patterning board.
