[QUOTE="Rijndael, post: 310844, member: 9298"] A change in temperature could cause a change is muzzle velocity. What your experiencing is most likely air density changes. I generally track that with my Brunton (you can use some Kestrels), using a calculation called Density Altitude. If you just use the elevation and temperature, you're missing one big value .... pressure. Here is a write up: [url=http://www.arcanamavens.com/LBSFiles/Shooting/Downloads/Baro/]Barometric Pressure and Ballistic Software[/url] I generally shoot at 330'. It's not uncommon for my Density Altitude to read -500' in the winter, while getting to 2500' in the summer. [/QUOTE]
