I am a lifetime bowhunter. Well this year I must have done something to my shoulder and elbow. I can hardly pull back my bow. I have no idea how I will be able to shoot. I am thinking of buying a crossbow but I have never even shot one before. Any suggestions on where to start? What are the models I should look at? I hunt archery quite a bit including usually a solid week during the rut. Thanks for your help.
