Regular readers know that I spent some time several years ago experimenting with handgun cartridges in lever carbines, specifically, in the .357 magnum.
Junior and I did some work in this regard, and if you follow the links, yo can see it here, and some more here. Suffice it to say that both Junior and I regard the .357 magnum as perfectly capable for deer-sized game out to about 100 yards, especially when fired through a lever carbine.
As it turns out, the Lucky Gunner recently revisited the question, with better equipment than either Junior or I had, and came much to the same conclusion. In both cases, the .357 and .44 magnum showed the same energy at 100 yards from a carbine as the same rounds showed at the muzzle when shot from a 4" revolver.
The video below is interesting, if only because it tells me what I've known of years, that a handgun cartridge fired from a lever gun is potent medicine indeed, with the proper ammunition.
It is good to see our early work validated.
