FYI, is shot the howa previously at extreme cold -15 degree c and it was 28 fps slower than above zero type temps. Same ammo. Good data I figure should be preserved here. Im sure most powders do this to some extent. But for those northern or winter coyote hunters dialing them up...keep in mind. Those super cold days you may need an extra click at 500.
