I took a look at the Elmer Keith load I had developed, used, and tested in the Model of 1926 revolver all those years ago, considered the recoil experienced in shooting the load, considered the work required to again work up to such a load, and then looked at my now 86 year-old revolver, and demurred from again revisiting the Keith load for testing for this thread, even though some 250 grain cast lead bullets made to genuine Keith specifications are on hand. I'm older and maybe, just maybe
a little wiser. Keith may have respected the Triple Lock for its strength and ability to handle heavy charges, but there ain't no way I'm going to crowd things in my 107 year-old Triple Lock.

If you want to know more about the Keith load then research it online for I'm not tellin'. This load was carefully worked up in a 5-inch Smith & Wesson N-Frame revolver. Due to the revolver's configuration, with the thin service stock panels common to an earlier era and the lighter weight tapered barrel of that era, working up and testing the load was unpleasant. The load gave a surprisingly abrupt and stinging recoil. While it would be amply effective for personal defense in the right revolver, its best use would be as a short range big game hunting load for the dedicated .44 Special revolver owner. It would best be used in modern Smith & Wesson N-Frame .44 Special revolvers with
more hand-filling stocks, modern Colt Single Action Army revolver in .44 Special, Ruger .44 Special single action revolvers built on the basic Black Hawk frame, or else any .44 Magnum revolver.
Personally, I don't even want to be around if someone intends to fire this load in really antique .44 Specials, the Charter Arms Bulldog, various Smith & Wesson L-Frame 5-shot .44 Special models, or various Taurus 5-shot .44 Special models.
*Not suitable for Charter Arms revolvers or antique revolvers (I wouldn't use 'em in one).
Is There a .44 Special Revolver In Your Future?
It's hard to say. Currently, compactness, light weight, and high-capacity are the order of the day with most shooters. For the person who primarily owns and uses handguns for self-defense needs as most perceive them the .44 Special revolver will not appeal. The modern non-handloading shooter will not be satisfied with the .44 Special as it is one of the more expensive cartridges one can support through the sole use of factory ammunition.
On the other hand: if one is a student of shooting and enjoys meticulous handloading, if a sense of shooting history warms one's heart, if the addition of a bit of exclusivity to one's firearms collection appeals, if one seeks a very well-rounded handgun cartridge that is just a little bit different than what the crowd admires, then the .44 Special stands ready to imminently satisfy.
