A couple weeks ago I shot my bow through a chrony and got 247fps ave with a 505gr arrow when the temp was about 40-45 degrees. Yesterday I tried it again when the temp was about 20 degrees and got 242fps ave. I guess that kinda makes sense as everything seems to get stiffer as the temp drops, but as I will use this bow for hunting i would like to know if this is normal and if you guys practice in colder weather due to the effects of the cold weather on a bow? Thanks in advance.
