Provided you can reliably get good bullet placement, the .357 Magnum in a rifle will work fine on deer, out to the range where the muzzle energy and velocity are down to the same level you'd see in a 4" revolver at the muzzle.
For example, with my 20" Rossi 92 short rifle, I get a muzzle velocity of 1820 fps and 1170 ft pounds with Federal 158 gr JSP. The time of flight to 175 yards is .35 seconds and that load drops down to 1277 fps and 570 ft pounds - which is the same as 4" revolver performance at the muzzle. That also gets it momentum and Taylor KO scores of 28 and 20.
Trajectory wise, with a 150 yard zero, it will have a maximum mid range trajectory of 3 3/4" at 85 yards, and will be 4" low at 175 yards. Accuracy wise, with a Marbles tang sight and Lyman 17A front sight I get 2 MOA to 2.5 MOA accuracy at 100 yards with both my 20" short rifle and 24" rifle Rossi 92. That's 3" to 3 3/4" at 150 yards, which is as good as or better than most revolver hunters can shoot at 50 yards.
Practically speaking, that lets you hold on a deer sized target, without covering any of the vital zone with the front blade. If you're thinking 100 yards as your maximum, it gives you the ability to estimate the range wrong by a good 50 yards and not have it affect the shot. If you know your business, a 150 yard range is still very reasonable, still allowing for a 25 yard range error.

The .243 Win with a 100 gr Sierra BTSP has a 5" point blank range of 345 yards with a 290 yard zero with a time of flight to 345 yards of .4 seconds where it has 2,250 fps and 1,124 ft pounds. That results in momentum and KO scores of 32 and 7 - a bit more momentum, but a significantly lower KO score than the 158 gr .357 Mag at 175 yards.
Since no one complains about .243 performance at 345 yards, there shouldn't be any complaints about the .357 Magnum fired from a rifle at 150 to 175 yards.
The average .243 Win rifle should be capable of 1 MOA accuracy, so it'll produce a similar 3.5" to 4" group at 345 yards.
Practically speaking then, the .243 has about twice the effective range of the .357 Magnum fired from a rifle, with perhaps a bit less effectiveness in the outer half of the 0-345 yard range compared to a .357 Magnum at 150-175 yards.

I have a single .243 Win rifle and quite frankly it sees very little range time. Unless the maximum anticipated hunting range is going to be in excess of 150 yards, it'll get left home every time. I prefer to carry one of my Rossi rifles in .357 Magnum, or one of my pre-64 Model 94s in .30-30. (2 MOA accurate, 4" high at 100 yards with a 200 yard zero, 1,570 fps and 813 ft pounds at 200 yards, momentum and Taylor KO of 33 and 10).
