I too have a crossbow - Excalibur - recurve type. Was lucky enough to get a deer with it this year. Shot was about 20 yards, complete pass through and the deer went about 5 yards after the shot with the arrow burying about 15 inches, almost up to the fletching, in the ground.. I hunt the deep woods, so getting a 100 yard shot is rare. Even so, with a crossbow the effective ethical range for me would be about the same as a vertical compund bow - about 40 yards. 50 would be the max I may consider; but everything would need to be perfect, a solid rest, the wind, the deer being still, etc.
Even though someone may be able to hit a target at 100 yards, it doesn't mean it equals a shot that will result in a clean kill. Factor in also the movement of the deer between the time the trigger on an Xbow is pulled and the arrow on its rainbow trajectory gets to the deer.
I do love my crossbow and think that for young, old, physically limited or disabled hunters, it is great that NY finally allows them to be used.
Best of luck to all.
