[QUOTE="Jeff In TX, post: 27965, member: 1522"] Brent, Great post on the answers. I have 7 different ballistic programs at home. I found out later, most of them were written by the same individual for different companies. He just had to make them look different. From what I found out, these were sold to the bullet companies under their label. Jim Ristow who wrote the RSI program was the head ballistic engineer at Aberdeen Proving grounds for the army for many years. I understand that the new Chey-Tac .408 development is now using a new type state of the art ballistic program that uses Doppler radar and can track a bullet over 2500 yards. They're able to track the bullet over the entire range with a visible reference on the computer screen that can be measured at any point. Now I like to bring 100 rounds or so to that range and play for an afternoon to see what my loads are really doing. [img]images/icons/smile.gif[/img] [img]images/icons/grin.gif[/img] [/QUOTE]
