Yeah. Because it is a black-powder era cartridge, the 44-40 has never seen its true potential in commercial loadings and modern firearms. A lot of the old brass was what the call "balloon head", and therefore not suitable for anything but low pressure.

The article says it will put a 205 gr pill out the muzzle at 931fps. That is adequate for self defense.
