[QUOTE="WildRose, post: 659817, member: 30902"] There are some guys here with ballistic formulas and calculators that can probably give you a very close approximation with every ten degree change. In fact, you can probably plug that in to your own calculator or the one Len has on the site here and get very close yourself. If I were estimating though (which is most of my shooting) I would probably assume a steady rate as you are and adjust accordingly. On top of the burn rate change that altitude change is going to complicate things a good bit. Sit down with the ballistics calculators and set up some tables for a cheat sheet and see how that compares with the approximation. Then I'd head back out to compare both to some actual field data under conditions as close as you can get to your extremes. Take then an average based off of all three and you should be extremely close. [/QUOTE]
