This powder has been gaining some popularity over the past year. I am curious to know if anyone can speak about temperature sensitivity of RE 17. My gunsmith friend just gave me some firsthand indication that it may have some sensitivity issues. He found, when running it near max pressures, nearly 50 fps jump in ave. velocity when going from 55 to 85 F. Has anyone had similar results? Do you think temp sensitivity would be as much of an issue if you are running below max?
