Cold air is more dense so it slows arrow down, warm/hot air is less dense and has lift, so arrows start hitting higher vs. when zeroed in in colder temperatures. This is noticeable at 100 yards, but at medium range up to 50, hardly noticeable. As temperature warms up, the whole bow: riser, cams, string, cables, expand. So no impact on the arrow, but on the bow yes.

 

no

 

Ive never seen a difference out to 60 yards. From 90 to below zero (-20ish).

 

I shoot year round, hot to cold and haven't seen a difference for out to my max hunting or ASA distance of 40 yards.

 

Cold and heat effect YOU more than the equipment.

 

Probably does if you lab test it but you'll never see it.

 

**WARNING** just a heads up...

Between the increase in gravity due to freezing temperatures and the potential for BH failure for the same reason all hunting must cease at 40 degrees....plan accordingly. Your welcome.

In case you didn't get the memo.

 

I have always aclimated my bows to the temperature before shooting them. I would put them outside the tent while eating breakfast while on a hunt hen freezing. In Canada, we had a 25M tournament on a curling rink and we would place our bows inside the rink for at least a half hour prior to competing.

The reason was that the material in the limbs became more dense or faster when very cold and less dense or slower when hot. I still see the differense on a 115 degree day in Arizona. I will place my bow into the garage overnight so that I would not take the bow from air conditioned temp to extreme heat. I might be a little picky but I have also seen a difference between a couple thousand feet of altitude also. My arrows will group a few inches higher at 80 yards on a cold morning in Flagstaff than they do on a hot day in Phoenix.
