There are several reasons that a crossbow is easyer.

1 sight it in ,practice a little to know the drop at different ranges and for get it till you want to hunt .Nothing to practice ,just pull the trigger when the sights or red dot is on the target.
2 After the sights are set or the red dot is sighted in it stays sighted in over the summer . Just shoot a few bolts to refresh your memorey of drop.
3 With the electric or crank cockers ,even some one that has little arm strength can hunt ,just have to hold up the crossbow.
4 It is easyer to be accurate with a stock , sights and not having to hold the string back .
5 It takes less movement to raise the crossbow and pull the trigger than to draw a bow.

I hunt with a bow most of the time ,but also use a crossbow .
Last year hurt my shoulder and could not pull my bow for 6 weeks ,so I hunted with my crossbow.
But with a crossbow it is a lot harder to still hunt heavy cover or standing corn.
