To answer your questions first no I haven't heard and penetration of the should on an Elk or larger animal is certianly possible with a match grade bullet but, not the type of shot I would take regaurdless of bullet type on an animal of the sizes you are talking. You see along with using the best bullets etc I can I wait for the optimum shot and the one you mentioned would not be it. Having said all that I guess I should have added (depending on the cartridge you are using and the distance from the animal you are.)
