Good timing...I was just working with a friends T/C Contender in 357 today.
Shooting a 158 grain semi wadcutter at 1,350 fps the 357 is a really flat shooter...much flatter than I expected.
Hitting milk jugs at 100 yards was easy...sighted 2.5 inches high at 50 yards it was dead on at 100. With this load it fell below 6" at about 135 yards.
Your particular load may be different though, you'll need to know the exact bullet and its muzzle velocity to get a decent prediction on its trajectory.
