I work with cow horn and NO WAY would I suggest that, It would stink to high heaven and probably knock you on your back side. Could even have some very bad long term effects being that horn holds a lot of bacteria. as for deer antler, I lot of folks doing the rendezvous thing make deer antler pipes, but they dont use them a lot. I heard from a doctor that it is not a good eidea to smoke out of one that when it gets hot you may end up inhaleing burn antler and he said that wouldn't be good. The one that was mentioned was the one I made, in the cob pimping thread and I only turned a finial for the bottom and was not in contact with the burning tobacco.
