If you're looking for a weapon that's entirely pre-hardmode than you're options are pretty linear. You'll most likely end up using the Star-Cannon considering it has ludicrously high base damage at the cost of stars for ammo. If you're willing to look into early hardmode weapons you'll probably have a far easier time. The best weapon to fight the Destroyer early on is still by far Golden Shower because of how many hits it can land with a single cast.
