Shoot it in the face with spread 3 for 2 minutes until you break it's face and then leave the quest. Bam, you'll either have a horn or a veil. Most of the time it's a horn. 2 minute farms. Easy peazy.
Also I never used HBG (or any ranged weapon) until AT Xeno came out, and I gotta say, it's the easiest weapon in the world to use. I hereby dub it the noobstick.
