At this point, the crossbow seems a true "wonder-weapon" to me. Here in NY, they only gave us the last couple weeks of archery season so I just bought a cheap, "entry-level" model ($250 Barnett Recruit). I was very impressed with the way this compact x-bow handled. It is only about 12" wide when drawn, and not at all front-heavy. It actually handles as good as my Ruger 10/22 carbine rifle. I was even more impressed with how accurate and how flat it shot, right after I put it together. It hit only about 3" lower at 40 yards than it did at 10, and all 3-shot groups, taken from a rest at those ranges could be covered with a quarter (definitely don't shoot at the same spot with 2 arrows however, or you will be buying new ones).
I only shot it once at a deer (6 point buck), which I judged to be 50 yards away. I aimed high-lung using the middle dot on the red-dot sight (all my 40 yard and under practice had been using the top dot). The range turned out to be 59 yards when I paced the distance to the part part of the shaft the buck snapped off with his front leg, taking the expanding 125 gr broadhead and the other 7" of the shaft thru the heart. He folded up and died after a 30 yard sprint.
My "baby" x-bow delivers 300 fps speed and has a 135 lb draw. That combo only gave about 8" penetration on a deer at 59 yards., so I would limit it to 50 yard shots in the future. When and if our state loosens up and gives us the rest of archery season, I would probably spring for a little more speed and draw weight. 330 fps / 150 -175 lb draw would probably be enough to make it a legit 60 yard weapon with enough remaining energy for a "pass-thru".
There is lots of bs out there saying that x-bows are not that much more effective than conventional vertical compound bows. Nothing could be further from the truth. In my hands anyhow, the crossbow, fired from a rest, and using telescopic sights is about 5x more effective on fixed targets, and 10x more effective on live targets. I will likely never pick up a vertical bow again. The white man should be thankful the Native Americans were not armed with such effective weapons, these things are scary lethal.
