I would never loan out a bow or a gun I was planning on using that season. Even if he has the money to replace you would still lose a lot of hunting time and who wants to deal with replacing gear during season. Like was said my old back up bow I would consider loaning out or my old 870 that never leaves the safe might get loaned out to someone I really trust. But as with anything of mine you can borrow it once, if you need it twice you should go buy it.
