I propose that the afformentioned armored T-Rex not be armored with metal but rather a combination of composite armor and bullet resistant nylon fiber. That could in fact stop a large caliber round especially taking into consideration that one could armor a T-Rex with such materials fairly heavily.
Also, you don't shoot an animal in the head. You shoot an animal in the heart and lungs. The head is a much smaller target and succeeding at hitting the torso is much easier. If you hit the heart, you can kill even a faily large animal in a matter of seconds. If you shoot an animal in the lungs, it won't be able to breathe.
However, considering the target (armored T-Rex) you'd want to use a higher velocity round with a much higher mass... Something akin to a 25mm cannon would do. Also, high-explosives are extremely effective against armored targets due to the fact that the shockwave would turn the target's armor against itself, crush the body and force the skin, bones, and muscles into vital areas; causing massive internal trauma. High-explosives can be thwarted with reactive armor on the other hand though.
