hi its me again, and I have got 2 more historical questions?

1)what was the fastet bp rifle catridge?
2) What was the most powerfull black powder rifle catridge ? ( which bp rifle had the highest muzzle energie)
 
From "Cartridges of the World: Ninth Ed" (Barnes)-Fastest I could find was 577/500 No.2 BP Express with a velocity of 1925 ft/s and energy of 2800 fpe, Most powerful was a 4 bore (or 4 guage) with a slug traveling at up to 1500 ft/s and an energy of 7,054 fpe (honest!). The most powerful and fastest military blackpowder cartridge I could find was the 9.5x60Rmm Turkish Mauser with a velocity of 1758 ft/s and muzzle energy of 1950 fpe. The 4 bore used an 1,880 grain bullet and used 380 grains of black powder.
