GUDSUN - compounds can kill a deer "way out there". Problem is, Xbows should be the last piece of equipment to try "way out there". One simple reason. Most bolts are LIGHT, very light. People are infatuated with Speed and means very little when coming to hunting. It's well documented that the faster an object hits, the faster the object slows down. It's called resistance force. That said, you can try a 60 yard shot, but with 90% of the bolts out there your penetration will not be as expected. It all comes down to ethics. If people, ALL HUNTERS no matter what piece of equipment would keep a kill zone small, say within 30 yards we would have less wounded animals or vitally hit animals that get away because of only an entrance hole or bad shot due to distance. I kill 4-6 deer a year and I know over 30 years of bow hunting every one was 30 yards of less. In the past 10, I can't think of one over 22 yards.
back to my point, xbow bolts are light, don't try and be a hero because you hear others doing it. They will learn their lesson a few times and hopefully change their thinking. If I shot a xbow, i'd be running a min of 150 grain head. Just my opinion though. Speed is not the key to killing animals.
I'm also not saying compounds should be shooting long distance either. My point was weight of arrow/bolt. arrows by default typically are close to 350 grain by accident simply because of length. If you figure out a carbon bolt at 22 inches, 45 for nock, vanes, insert, 100 grain tip, you aren't pushing much.
