I am going to have to get back out to the friend's farm to use the Oehler 35P at 7 yards. It did much better at chronographing paper-patched, duplexed-BP loads with grease cookies, but is impractical at the public range due to terrain and lack of "elbow room."
We have conquered the .458 Lott, well and truly. Most interesting now, for me, is to recreate the entire history of practical rifle ballistics, using the .458 WM. Single round ball, BPCR, Nitro Express and beyond, plus a shot-capsule load for pests, the usual domain of the .458 Lott. And one more .458 Winchester Magnum rifle, a Winchester M70 Classic (or FN/Portuguese) stainless rifle with all the bells and whistles. Maybe a stainless full octagon barrel with barrel ladder, Beach combo front sight, vernier sight on heel of synthetic stock, and the Near 25-MOA Picatinny on the action. A 10-pound limit with no scope, 24" barrel, fun to shoot. A round barrel of No. 5 sporter contour will do it easily, need to do some figuring on the octagons and barrel sights.
That octagon barrel would look even more awesomer with a timed octagon muzzle brake. 😁😀
