I've shot 9.3s for 12 years. I have reloaded many varieties of bullets (in multiple calibers) and test each over the chrono and through water-filled milk jugs. In the 9.3x62, Woodley, Lapua Mega, Hornady, Partitions and Privi all launched (mostly with (RL-15) at 2150-2225 fps passed through 6+ milk jugs. Same for 250 Accubond @ 2350 and the Speer 270 Hot Core at 2450 (BL-C2) also passed 6 Jugs. Retained weight differed from 71% to 83%. 10 years ago Megas were my fav and cheap as dirt. No more. I could not get 286 Barnes velocity high enough to keep them from tumbling because of case capacity. 250s performed well but I only loaded some solids so it's unfair to compare. From my experience, I would hunt African plains with Privi though it would not be my first choice. In 2013 I safaried with 300 gr A-frames and DGS with PP-2000 @ 2250 both with over 6 jugs for giraffe and others. In 2017 I used 250 gr Nosler Ballistic Tips (Pale Green Tips) on Eland, Zebra, Hartebeest. Penetration was not an issue but I'll stick with 286 in the future. It isn't hard to compare for yourself and personal confidence is what is important before pulling the trigger.
