[QUOTE="Darryl Cassel, post: 23027, member: 34"] Hello At only 1000 yards it seems to matter ONLY when a drastic change is seen in temperature AND altitude. It dosen't seem to make that big of a difference when in the hunting fields and what I have noticed at the 1000 yard mark. Over 1000 yards and out to 2000 yards it is noticable. Most people carry their ammo in the pocket of their down clothing in the winter to keep it a bit warmer and keep them in an ice chest, chilled down when it's 90 plus. Is it really needed? Normally the ammo temp is the same as the outside air if you have your ammo in a box and outside with the rifle. I think if your shooting HOT winter time loads, you better chill them down when you take that SAME ammo into 90 degree heat. The computer ballistics program is figuring a temperature of the outside air and to an extent the same ammo temperature. For me, I have not really seen a BIG change within 1000 yards unless the temperature changed by 40 or 50 degrees and also when we combined that with a new altitude location of several 1000 feet. If your talking about the near same temperature and just a slight elevation change, theres not much change in trajectory. It takes a drastic change in most cases to see a BIG difference. This has been my experiance. DC [ 08-08-2002: Message edited by: Darryl Cassel ] [/QUOTE]
