[QUOTE="dfanonymous, post: 1772696, member: 97050"] To be clear, since you have some interest, this is under the assumption that the litz formula is correct. Which it’s not in all cases. Litz’s formula is of linear value, as discussed above, SD is not linear. This is a complex topic that in even the best of math equations still contain at the least a a certain % of error. Hornady 4dof uses a flat rate. Also a linear equation. This is also not correct. These are based on TOF but with a over lapped flat rate value. Simply put theres more to the equation. Hence why 1% to 2% of drop is a little closer to reality. I’ll link below as to why. It’s a over all complex subject if you aren’t a nerd. If you are then here’s some material: [URL]https://www.researchgate.net/profile/James_Boatright/publication/327582502_Calculating_Yaw_of_Repose_and_Spin_Drift/links/5b98360b299bf14ad4d099da/Calculating-Yaw-of-Repose-and-Spin-Drift.pdf?origin=publication_detail[/URL] [/QUOTE]
