Quick question, can the cold air warp an arrow. My friend was shooting her bow today and couldn't group her arrows. Last week she had no trouble with her groupings. The arrows being used are junior composite for 30 to 50 lbs.

I cant speak to the physics aspect, but was your friend a lot more bundled up because of the cold weather, perhaps the added layers hampered her form.
interesting question, I know that it can affect bullet zeroing. like if you zero a rifle in warm temps it will impact higher in the cold because the air is less dense. so with that said I could see arrows being higher but it shouldn't affect the group size itself. im new to bows though so I don't have much of an answer for you.
Maybe the cold is affecting her. Shivers! Usually its not the equipment but the user!
Could the cold make the arrow a little smaller? As.most things contract in cold.. I don't know much about how an arrow flys..
First cold air is more dense then warm air. Powders burn slower in cold temps then they did when it was warm.. You may be thinking of zeroing at a low altitude and then shooting at a higher altitude and finding the Point of Impact is higher because then air gets less dense the higher you go.Quote:

carbon has extreme resilience to temp change so by the time you shoot from your stand they would have climatized and shoot consistent

This seems very likely to me.
X2 The cold stiffens the carbon and increasing it's spine.Quote:

Fibreglass arrows however are very cheap, and my understanding is that fibreglass can become brittle in very cold temperatures and develop "stress cracks". This would not change their trajectory however, what would happen is they would snap more easily - what I like to call "catastrophic arrow failure".
What is far more likely is that it was all in her head. Lack of concentration, lack of sleep, frustration, distractions, hunger, etc. can really mess with an archer's head. A mental distraction can cause a person to make minor mistakes to their form and make it near impossible to make good arrow clusters.
Or maybe she was just wearing a different jacket because it was cold outside and the jacket was rubbing against the bowstring during her releases and/or messing up her form somehow. That is probably the simplest answer.
Here is a list I made of common mistakes people make during releases that can mess up their arrow clusters.

Hey cardiotrek,
Thanks for your website, great info on there!
Cheers Ian
When living Bethel Alaska in colder hunting days and my target shooting my arrows hit low with longbows,recurves and even cross bows we over came this by changing brace heights lower on all 3 of these bows I keep notes were to set the proper Brace heights based on Temp range.
