A few thoughts on this:
If you want to shoot below minimum loads you can use cotton balls to make a wad above the powder that will compress the powder against the primer and keep it there when you seat the bullet regardless of movement or orientation. The problem with low level loads is the bullet becomes an obstruction. In a normal load the bullet jumps to the lands with good velocity and continues to be forced down the bore. With a light load the bullet jumps forward but not with enough pressure to keep it moving, it jams into the lands, pressure increases, burning rate increases, and now it is in a closed obstructed container unable to get the bullet moving again because it is jammed.
A 44 is a potent round but most wouldn't consider it abusive in a SRH. Recoil management can be taught/learned, you don't just have to accept where you're at with it. Things like a proper grip, bore and forearm alignment, concentration on accuracy techniques like sight picture, trigger control, and breath control all can remove the perception of heavy recoil. There are also drills that help recoil management. Most recoil issues are more mental than physical. Wearing a glove will help substantially and a rubber grip that fits your hand. In hunting I went from 357 to 44 to 454 in a SRH. I also now use a 4" 41 mag in light titanium for packing in Alaska and I've taken a mountain lion with it, that is simply brutal compared to the 454.
In 44 I started with the 240gr. But I noticed the bullets seemed to just pass thru with little shock, deer would run off, very nice blood trail, but the deer would bounce off as if they weren't hit, similar to a hard muzzleloader slug. So I went to the Sierra 180 JHC hoping for more expansion and shock. Gave me less recoil, higher velocity, and a flatter trajectory out to 100. I "think" it helped with the deer but I never recovered a 180 or 240 to know for sure, always a pass thru. From the Sierra site "Designed for the hunter requiring accuracy, penetration and dependable expansion from a 44 Remington Magnum revolver, Sierra introduced the 180 grain #8600 in 1970. These bullets were upgraded with Sierra's PowerJacket in 1982. The dependable Jacketed Hollow Cavity and PowerJacket design makes these bullets extremely versatile. They are true magnum bullets, featuring a heavy jacket and 1 1/2% antimony core, yet they will expand reliably at 44 Special velocities. These bullets are extremely effective on up to deer-size game."
