shotgun slugs for bigger game

[bullfrog99]

just curious, i've reciently shot a whitetail with a brenneke gold 1 3/8 oz slug, and the large buck fell like it was hit with an artillary piece. i was just wondering, would a slug be useful for game larger than big whitetails,
i'm not talking bear, but something in the range of a medium sized elk at 50 yards or so?

Bullfrog , not only Elk but what about Moose ? I've only hunted deer with shotgun slugs, but if you could get within 50 yards why not Guys huntem with bows, muzzle loaders and handguns. I think that Brenneke slug would pack more wallop.
