It seems to me that any negative a crossbow may bring can be argued. The same can be said for any positive. While I don't see any in your face negatives for using a crossbow during archery season, I dont see any real positives either. I dont think that adding to the already incresing numbers of archers in the woods during the archery season is a real positive.
There is an archery season and if you want to hunt during it in a state that doesnt allow crossbows, then pick up a compound with all its bells and wistles and hunt during archery season. If you can afford a good crossbow, why buy one over a compound bow, if they are so close in comparison? If you can use a compound what is the point in pushing a crossbow?
Why add another weapon? There are plenty of options for all types of hunters. Every form of taking an animal has its own unique elements. To me a crossbow doesn't add any new unique element to a hunt, but is seems to rob some of the uniqueness of archery hunting.
A cross bow is a hybrid a cross between a gun and a bow, it isnt really a gun, and it isnt really a bow.
I just dont see the point in adding a weapon to the choices.
If you want to hunt during rifle season, get a rifle.
If you want to hunt during muzzle loading season get a muzzle loader.
If you want to hunt during archery season, get a bow.
There are several types of bows to choose from, the line has been drawn in most states not to allow crossbows. The line has to be drawn somewere.
