The high-power military-grade Doppler radar will still be best because the continuous velocity numbers for all points in time eliminate any guessing at best breakpoints in the values. But, as Litz says, even a box of match bullets can exhibit 3% variation in BC, so there's a limit to how precise it is useful to be with BCs. Plus, I, for one, can only access a 1000 yard range occasionally, so I need workarounds.

I saw an argument between Bryan Litz and a European shooter who was a member of either a police or military sniper unit. This was on another forum some years ago. The European's outfit used equipment that used something akin to or evolved from Art Pejsa's method that he published in Precision Shooting toward the end of that magazine's life. I recall they were firing to measure drop at half their maximum range to fit data to project drop at other ranges, which is was what I recall Pejsa describing in that article and which he claimed would get you drop within half an inch at 1000 yards. The European's argument was that BCs were antiquated and less accurate by comparison. Of course, he only had to worry about one bullet fired from one gun. If you want to make the information portable, BCs are still, by far, the most compact ballistic information.

I think that argument must have been over ten years ago. Smartphone memory and computing capacity have grown so much since then as to gradually obsolete tables and they have the capacity to use the individual bullet drag functions determined by Doppler radar. Lapua has made those functions available for its bullets for over a decade and Hornady is now generating them for other brands, especially its own.
