Welcome to the wonderful world of bowhunting! To determine if you have enough bow to hunt with we will need to know what your draw weight is. A good minimum weight for deer sized game would be 40 lbs. Check the NY DNR for info on legal requirements in your state. Another and probably the most important thing is to make sure your bow is set up right to fit you. And practice as often as possible. We owe it to the animals we hunt to be proficient with our weapons. I have learned so much on this site about bowhunting in the 2 years I have been coming here. Ask as many questions as you need to. We will do our best to help you out.
