[QUOTE="liltank, post: 581148, member: 13275"] The angle compensation can be done by you in the field if you use a calculator or a shooting program. You will need a cosine/angle indicator that mounts to your rifle. It does make a difference in the angle. If you find yourself shooting a steep angle, it actually shortens the distance the bullet needs to fly. For instance, a 220yd target I shoot at, has a .98 cosine. It shortens the distance to 215yds. Its only a drop of 5yds, but at longer distance, it can make a real difference. Temperature will effect your drops. No some of that has to do with powder burn rate speeds at different temps. The other part has to do with air density. Tank [/QUOTE]
