[QUOTE="Pdvdh, post: 289486, member: 4191"] [U]Eaglet[/U], Thanks for correcting me where I was wrong. You're educating me also! [U]John[/U], I tried the free 30-day trial of FFS while I was investigating ballistic software. I ended up purchasing PB LoadBase and for me, LoadBase is easier and more straightforward than FFS. PB LB offers more flexibility, provides more information, and has a convenient method of allowing the user to compare (play with) different theoretical loads, bullets, velocities, BCs, drifts, etc. PB LoadBase's Analyzer feature allows for the calculation of the DC (drag coefficient) by chronographing bullet speed at four different distances, which must be at least 100 yds or more apart. The farther apart the better. A G1 BC can also be calculated based on bullet speed chronographed at two separate distances. Obtaining the correct DC for a bullet allows the software to very closely predict POA corrections. When I went through this process with my 300 Win Mag, my POI was right on the money with the predicted POIs. The farthest I chronographed was at 989 yds and I didn't like that one bit. Expected my skyscreens to explode at each and every shot. I should get some armor resistant steel plate to protect my chrono skyscreens at those extended distances. Now - you don't have to shoot at four distances and obtain velocities and calculate DC for use by the program. That's just a feature available that has the potential to improve the accuracy of the input to enable really accurate output/POA corrections. You can also simply use the G1 BC provided by the bullet manufacturer and tweak the DC (drag coefficient) to match your measured drops and end up with a good fit. I can't make any comparison to Exbal - never used it. I'm not on any mission to knock FFS. Just expressing my findings and preferences based on exposure to, and use of, both software. Others may reach a different conclusion. Now when you complete your research into FFS, we expect to get some feedback. Let us know what you decide and why? What you liked or didn't like? [/QUOTE]
