I am using the following load in a 22", Stiller Tac-30 in 308. I got 2638 FPS at 87 degrees in the summer and in the winter (for SC) I'm getting 2575 at 55 degrees. Any thoughts on if this is reasonable for temperature based velocity change using Varget ? It was more than I expected ? Strings of 5, 12 SD, clocked with a Magneto-speed.
