RE: Crossbow or Cross-Blows
first off check your state laws. here in Florida you can only use a cross bow during general gun season unless you have a special permit. to get the permit you have to have a doctor sign a state form saying your disabled to the point that you can't pull back a regular bow. once the state form is signed, the state will issue you a permit allowing you to use a crossbow during archery season.
yes, crossbows are extremely accurate and powerful. they are more than capable at taking deer at distances that an average archer shoots. as long as you sight it in properly and make a good shot, it's as humane as any other hunting weapon.
