[QUOTE="royinidaho, post: 230536, member: 2011"] RL-22 in 270 Win. - 130 FPS velocity reduction from 70* summer temp to teens in winter. With powders such as IMR 7828ssc I load to max in less than 70* temps and don't worry about it except in my long range guns where I am a bit more particular. When I chrono a given load @ lower temperatures it is always lower than in warmer temps. If it is sufficiently low I enter the lower velocity into the drop chart program and make a new drop chart. I'm not one to have a cold weather load and a warm weather load. I'd invariably get'em mixed up sooner or later. [/QUOTE]
