In 2007, I made a card for a challenge where I use a .22 bullet as my embelishment. I think that's the most creative I've ever been. I used Noble Deer from SU!, but any deer image would work.

Other things a hunter might appreciate is a camping set, with fire and a tent. Or even horses for those hunting trips that happen on horseback.
A fishing/hunting theme might be appropriate, as well. My DH loves to hunt in Alaska and the locals take the hunters on boats and they hop from place to place in the boat, get off the boat and hunt the area then get back on the boat.
