[QUOTE="Mike Matteson, post: 2980268, member: 101791"] I have been talking about this for a long time on temp sensitive powders. All powders velocity change with the temperature changes. Some far greater than others. It's more so with longer range shooters. 50fps can change your POI as much as 14" @ 1000yds. Some of us hunt in weather that varies as much as 130' between high and low temps. Depending on what powder you are using that can be over 130fps change or it could be only 10fps. The other is your powder load can go from safe to over pressure depending on what powder is being used. When the powder load was figured out for your rifle is it done in cold weather mid temp or hot temps. Now I will say I load hot, but no rejector marks or creator primers. Primers are flat, but that where I stop. Most of my load work up is during means temps. There is powder that don't change much in temperature change. I might not get the velocity that can be achieve with other powders, but at the same time I don't have to worry where my POI is going to be. [/QUOTE]
