[QUOTE="noone, post: 632714, member: 15610"] I was using 68.5 grains of IMR4350 in a 300 Win Mag, Winchester brass, Fed 215 primers, and a 190 Sierra match king. In winter, the load is very consistent, accurate, and gives 2960 FPS. When the temperature hits around 80-85, the velocity jumps to over 3050 FPS, so after 2 shots over the Chrono, I decided to save the rest of that lot of ammo for next winter's shooting. And it worked great again. I have a few months before temperatures start getting too hot for me to want to use that load again. [/QUOTE]
