Out of curiosity to see just how anemic a couple of factory .44 magnum loads were, I took two Federal loads, (44A) 240 JHP, and (44B) 180 JHP. The idea was to shoot down into an open 55 gallon drum filled with water, see what happens. Fire the 180 JHP first, as it was sure to disintegrate. If one of the bullets had a chance of punching through the bottom of the drum, it would be the 240 JHP.
Revolver: Redhawk .44 mag 5-1/2".
I climbed a stepladder, mainly to get away from the splash, and fired a 180 JHP @ 1610 fps, from about 5 feet above the drum. BOOM! I got soaked. Fragments of jacket and core lay on the bottom of the drum. Amazingly, the bullet, or what was left of it, put a 1/8" dent in the floor of the drum.
Add a few gallons to top off the drum. Next, fire 240 JHP @ 1350 fps. Get soaked again. The 240 JHP mushroomed huge. The bullet made a 3/8" dent in the bottom, stretching the sheet steel to the threshold of breaking.
This was no comprehensive "test," just an experiment with two loads with which I'd taken deer, one shot each. The Federal 180 JHP involved lung shots only, with kills from the 5-1/2" Redhawk, a S&W M-29 4", and an M-29 8-3/8".
The Federal 240 JHP, fired from the 5-1/2" Redhawk, dropped two deer, a shoulder shot and a lung shot.
A note on bullet placement: I was for years a lung shooter, never had a problem. Elgin Gates, whose exploits as a world-wide trophy hunter will never be duplicated, was very big on breaking the shoulders. Gates said that high lung hits, particularly on large members of the African plains grazers, could lead to miles and miles of tracking. More than anything----dangerous game aside----it was high mountain goat hunting that caused Gates to concentrate on dropping an animal in its tracks. A goat could easily tumble off a ledge and fall thousands of feet, to be destroyed or unrecoverable.
Hunting in the South sold me on the shoulder shot. There are places, not necessarily swamp and river bottom, where thorn vine and kudzu are so thick you got to be a snake or coyote----or deer----to get through. Doesn't matter whether it's a rifle or a shotgun or a handgun, you don't want that deer leaving the scene.
