Name the Horror Movie again

[Jomb]

There is this guy. He is in a hunting lodge I think. Or maybe its just somewhere secluded. He has a gun. He is coming unhinged and I dont know why. There is a moose-head hanging on the wall. The man is hallucinating. The moose-head is laughing at him. It is very insane. The man is then laughing along with the moose-head while clutching a shotgun I think. He is crouched in the corner of the room and is sweating profusely and is a mess. I dont remember anything else at the moment. Yes, these sorts of movie snippets play through my mind alot.

I strongly feel that this movie would have been made in the 70's. Maybe late 60's, some chance of early 80's but that is a long shot.
