Immediately after the invention of the aluminum arrow and the compound bow deer refused to die when shot with primitive archery equipment. In fact some anthropologists with more letters behind their names than a can of Campbells Alphabet Soup have theorized that the reason our ancestors are extinct is because they starved to death waiting for compound bows and aluminum/carbon arrows to be invented. Too bad for Og, Grok, and Earl-Roy, Jr. when you think about it.
The brand new Primitive Archer Magazine (best magazine in the world) has an article on an elk hunt by the former editor of Buckmasters Whitetail Journal with his 46 lb osage bow and simple wood arrows. Granted, he shot at 10 yds and "clipped a rib on it's way in, passed thru both lungs and the top of his heart." The bull elk collapsed within 30 yds of the archer. The broadhead was a single bevel two blade cut on contact...certainly no mechanical Rube Goldberg contraption relying on digital technology, batteries, GPS, and a Macbook combined with a Swiss Army Knife.
What counts is matching the arrow to the bow so you get good arrow flight, minimum 40 lbs draw weight (depending on your state's regulations), and a broadhead that is so sharp anyone with good sense is afraid of it. That and practice, practice, practice at any and all yardage, from every position you can sit, lay, stand, or hover off the ground. You poke one thru the boiler room and that animal is on it's last countdown!
