In a 4" gun, the likely shot is 0-75 yards. At that range, I would probably go 240 gr XTP or Gold Dot to get more expansion.
If you will most likely shoot over 50 yards, I would go the SWC route.
I've killed deer out to 125 yds with a 44 mag, but mine was a 10.5" barrel Blackhawk. It is the same but different barrel length.
Don't expect them to drop like hit with a 30'06. They will run a bit and the go down dead, if you hit 'em right.
