Do we have a thread open with more discussion on folks temperature and altitude POI deviation experience? I would love to hear peoples thoughts on this. I shoot year round with up to 120 degree differances in temps and have some rough corrections worked up but results arent always consistent. Im just curious to hear more about what others are doing when the mercury drops, or rises. I have my SAC set at 3000ft, 60 deg., with the baro at 29.5 now summer temps will go 100 and its often 10-15 below come elk season at 8200 ft.
