I have harvested 7 deer with a 357 Rook rifle I built using a shot out Break action Muzzle loader frame. I use a Cast Boolit, a NOE 360180 WFN loaded to a very mild 6.5gr of 800X for a cronyed 1250 FPS out of the 17.5" barrel I used. Only 2 deer were inside of 50 yards. 3 were 125 plus. Complete pass threw and able to eat right up to the Boolit Hole.

The little rifle harvested 3 deer this past season in My 81 year old fathers hands. One of my Nieces was setting with him one morning and also harvested another big doe with it. Dad just smiles, It doesn't tear his arthritis apart. It has him out in the woods again.

The 357 mag with a solid hard cast wide flat nose projectile driven at a modest velocity will cleanly harvest any deer at what ever range you are comfortable shooting with it. I have an old weaver K2.5 on mine and it will hold 1.5 " all day long at 100, I am sighted almost 2' high at 100 it is minute of deer all the way to 150 with a dead on hold.
