[QUOTE="BrentM, post: 756068, member: 61747"] For example when I shot the new loads last weekend it was 47 degrees, 4125 feet, and the powder was in the truck as we reloaded in the field. The temp inside the truck was 60. I took the load to the rifle and popped it through the chrono. So zero would be 4125 and 60 degree's which equaled a FPS of 2975. Shooter know's this. So then if I am packing a mag full of cartridges and the outside temp is 30 we could easily assume the powder is going to be quite close to that as well. The adjusted velocity is significant. 240 fps difference. Seems way off to me with extreme powders. [/QUOTE]
