One Moose, several Elk and a bunch of deer needed no tracking at all when hit with a 6.5 Creedmore or .264 WM all with 140 PP's, 140NP's or 142 ABLR'S anywhere from 50 to 500 or so yds (before rangefinders). The one thing in common were zero marginal hits! One deer just ran 100 yds or so gushing all over the place but totally in sight the entire time. One deer shot at 384 yds with a CM and 143 ELD-X needed another one to stop moving so we could get up the extremely steep hill to him but he was not going anywhere after the first shot. All bullets either exited or were found just under the hide on the off-side. One bull elk took three 165 NP's from my 300 Wea. through the heart area at 175 yds and finally dropped in his tracks but oddly never moved after the first shot. YMMV.
