This silly idea came to me recently when reading about a straight-wall rifle scope. Said rifle scopes' holdover hash marks were put in place in the reticle based on the bullet drop tests from a 450 Bushmaster with a 250 grain projectile, 18" barrel, at 2200 FPS, zeroed at 100 yards. Each holdover is for 50 yards beyond the 100 yard zero out to 250 yards. Since all bets are off with holdover accuracy using different loads and a different caliber straight wall rifle, I wonder if anyone has ever designed a handload so it's ballistics match a scopes reticle holdovers...sort of reverse engineering. In this case we know what rifle caliber, bullet weight, barrel length, and FPS was used, and perhaps this information can be extrapolated to design a handload for another straight wall caliber rifle like 350 Legend that will have similar ballistics to the 450 bushmaster load used in scope's design so the scope's holdovers will be nearly as accurate for the different load and rifle. It's a silly idea but it sounds like it someone who loves reloading and dialing in their handloads may find this concept interesting. There is a big difference between a .452 diameter bullet and .355 diameter bullet (450BM vs 350L), so maybe this is harder than it sounds.
