On November 2008, Berger Bullets hired Bryan Litz as their ballistician. Bryan is well known in many sites for his knowledge in ballistics as well as his well founded scientific approach. All this is to quote some of the comments he has made in his website in reference to Coreolis effect and spin drift. Homepage of Bryan Litz - A Bravenet.com Hosted Site He also acknowledges the fact that there are not too many programs out there that will calculate for Gyroscopic Drift (Spin Drift) What has this to do with LoadBase 3.0? Well, a lot! LoadBase 3.0 is still in Beta but powerful nevertheless. Patagonia Ballistics says: Also: Here is how easy it's to run the program to obtain Spin Drift. Amazes me that we would barely scratch the surface of all LoadBase 3.0 does. I want to clarify that I don't work for Patagonia Ballistics nor do I get commissions or anything from them. I do this because I get excited with a great product that would help us all. In other websites I have read comments like "It could very well be that LoadBase 2.0 is the best ballistic program in the market." If you're a long range shooter, you owe it to your self to look more into it specially when the full LoadBase 3.0 comes out of its Beta mode. Do not be bullheaded, do yourself a favor.
