shooting a 260 rem. Tested at 60F two weeks ago and 30F yesterday. Loss of 30 FPS. 20 shots at each temp. SD was much wider at the lower temp going from 4 at 60F to about 12 at 30F. Barrel received exact same treatment before hand and both strings shot through two consecutive chronograph each time with consistent results. Same brass.
