hey everyone, i have a martin archery bow thats kinda old, at least ten years. i was wondering if i should use it for hutning deer, i don't know the draw wieghtbut i believe it's adjustable by tighening the limbs. i've been shooting it free eye and with no help but a release and i'm accurate up to 20 yards. also this is my first year hunting. should i just wait till i get a better bow??
