Big Game is very temp sensitive if you use any sort of a ballistic reticle. I quit using it in my 7-08 for that reason. I developed my load in spring at temps around +15c
and things were great, then shot it before a hunting trip in the fall when temps were below 0 and I lost 120 fps. That is fine if you use a straight duplex reticle and only shoot out to 200 yards.
Such has not been my experience.
Temperature stability is one reason I selected BG.
