300 Win Mag with a 220 SMK and a charge of H1000 spec'd to68k psi (5k over SAAMI) for the Mk248 Mod0 sniper load.

In case someone think's that's a dangerous load. . . .
SAAMI's .300 Win Mag service maximum probable sample mean pressure's 68.1Kpsi, so that load's at the upper limit of industry standard specs. Maximum probable lot mean pressure's 65.6 Kpsi.
The cartridge' proof load pressures are 85.5 Kpsi and 91.5 Kpsi, respectively. Few, if any of the fired cases are ever reloaded, so the danger issue's minimized.
