Looking at reloading some 95 gr. bullets for my .243 Model 7. The Nosler manual lists Vihtavouri N560 powder as being the most accurate in their tests. Somehow, I remember reading that the Vihtavouri powders are great, but very temp sensitive. I live in AZ where the day can start at 65 degress but climb to 105 degrees within several hours, so this becomes a big factor for me. Does anybody have experience with this powder, especially regarding temp sensitivity?
