I would have to say no because the question is for a .177 cal 'BB' gun. If you intend on hunting with air rifles in the .177 caliber, then you really should use pellets. Pellets provide much greater accuracy and are more humane than a BB.
First, check to see that you have a BB gun, and not a pellet gun. Both pellets and BBs are made in .177 cal. A pellet gun will not shoot BBs (in most cases) If your gun IS a BB gun, you will need a gunsmith to check it for damage, stuck items in the barrel, etc.

It all depends on the particular model. There are over 100 different models that shoot .177 cal BBs'
