Wow, I didn't even know that Doubletap made 9.3x62. Doesn't really matter I guess, I hardly ever buy factory ammo. I love rolling my ownWell, if you check out Doubletap's loads for the 9.3x62 they include one that's a 250gr TTSX @ 2650 FPS out of a Ruger M77 with 24" barrel. Now that's a pretty stout load..
No offense to my friends at DoubleTap, but I would chrono those loads before I started building drop charts. Their 10mm and .357 Sig ammo, has started coming up 100 fps short of claims on the box.Lots of max loads with the 286gr that are at or above 2600 fps. RL-17 and IMR 4895 will do this with the PRVI bullets. I use PRVI bullets and cases.
Europeans also run higher pressures than American standards. loaded Norma ammo in a European cartridge like the 8mm and 9.3, are hot loadings and real performers.
ON the 2600 and the 9.3x62, these heavy loads should only be used in modern firearms like the Rugers and CZ.
I'm trying to get Barnes to start loading more calibers in their Safari line, and I'm close to getting g the 375 Ruger a greenlight!
