I shoot bowling pins at my local gun club every other week with my Smith 629 44 mag 5" barrel open sight. My favorite load for that shoot is the Hornady 240 grain lead hollow point over 7.2 grains of Vihtavouri N-340. This is an easy "plinking" load. Very accurate and with enough force to take the pin cleanly off the table at 25 yards. ( even those really bad pins that seem to be a plastic shell full of sawdust)
For deer (and an occasional groundhog for practice) when I use a 44 mag it is my Smith 629 6.5" barrel with a Simmons scope. My favorite load for that gun is 24.0 grains of Vitavouri N-110 with a Hornady 200 grain XTP hollow point bullet. This load will put all 6 rounds in a 5" group at 100 yards shooting from a rest. It will also let you know that you have wrist joints.
It's a enjoyable round to shoot.
Now, I would take a 100 yard shot at a deer only if I had a solid rest to shoot from. If I were just shooting from my Stoney Point shooting stick, 60 yards would be my maximum with the Smith. But, give me a solid fence post or a nice oak limb.....
....different ball game!

Oh, I can't speak for WW296 as I have never used that powder, but for H-110, Bill is absolutely correct. NEVER use H-110 below (or above) the recommended charges. H-110 is VERY fussy if you drop below the low end. You can end up with a squib load...stick a bullet in your barrel...and shoot the next round with a barrel obstruction and that's the end of your gun AT MINIMUM!
