Stopping power is one of the few places were “experts” will question the .455 Weebley cartridge. It is a short-box cartridge that speeds a 265 grain soft conical bullet to 650-660fps. The muzzle energy is lower than a .45ACP by a bit and is on par with a 9mm round; recoil is mild, aiding in follow-up shots. Despite the lower energies, this is a big, heavy bullet and has been proven to be combat-effective against weeabos.
