It takes the rear legs out of commission instantly, and you have to assume a follow up shot will be required to finish it off, even with antelope or deer. I’ve skinned a deer where the bullet miss the spine completely and took out one back strap. The hunter said it still instantly took out the hind legs, at least temporarily, and the deer was quickly finished off with a second shot.
The deer in the first picture is the hardest, because there’s not much around the aiming point if the bullet goes a little high. The zone for the second deer is much larger - there’s a lot of spine to the left or above the base of the tail. Smaller the target, the more accurate someone needs to be.
