[QUOTE="Clint Idaho, post: 868894, member: 38561"] I used to load IMR 3031 and 4064 exclusively for the 150 - 168 gr range. Notice the I used to part. After purchasing a chronograph, I started to notice a wide variance in velocity for all the IMR powders in the different calibers. Usually only after the temp dropped below 20F. The powder I now load in the 308, 7mm-08, and 243 is Varget. Very consistant across the chronograph at any temp. Groups if I do my part consistantly under the 1/2 inch mark. Most would not notice the temp problem for normal hunting. But I spend a good portion of the winter calling coyotes. The variance was opening my groups up to around 2 1/2 inches once the temp dropped. I have not had this problem with Varget. Big fan of the 788, I have several 308, and 243's. Also the 223, and 7mm-08. Still looking for the elusive 44 mag. All of the 788's have been under 1/2 inch shooters. [/QUOTE]
