the 577/450 is the most powerful of the old black powder military cartridge, iirc fire a 500 grain bullet with 90 grains blackpowder. allways wonder why it dont get more attention as a hunting cartridge because its a blackpowder express.

Interesting the ballistics are given on the net as a 480 gr projectile pushed by either 85 grs of powder for 1315 fps/400 mps velocity.

The US contemporary of the .45/70, 500 grs projectile, 70 grs powder and 1300 fps.

Why is not more velocity achieved for the .577/450 with 15 to 20 grs more powder?

As has been remarked before on these and other forums, we endlessly hear of the 'great killing power' of the .45/70 even on cape buffalo, yet no one hunts with the 'ineffective' and 'sub-powered' .577/450?

Both seem equivalent and certainly useful for hunting medium sized game with reasonable shots.
