[QUOTE="J E Custom, post: 1791387, member: 2736"] I don't see much difference in those temperatures, but most of my hunting loads are loaded and tested in the same temperature range and it is only when I get into high temperatures that it seems to happen. One of my best/most accurate loads uses H414 and during hunting season is extremely accurate and holds velocity to 3010 ft/sec. But I am unable to go to the range when temps are near or over 100o because the velocity in the same load goes to 3155 ft/sec and is a hard load. I just wait to verity zeros with it until temps drop into the 60s. Cold weather doesn't have as much effect on powder except some are harder to ignite. In really cold weather I keep my ammo in my pocket just in case, so id don't have to load differently for the seasons. For the weapons I use during hot weather, I work up the loads in temps over 80o and when I see signs of pressure I back off to avoid high pressure. I have had good luck with most extreme powders, but even some of them will sneak up on you at times and go critical. J E CUSTOM [/QUOTE]
