Maybe of interest here. There is a restaurant in Jackson, WY, the Gunbarrel. Great steakhouse in a Western motif. On most of the columns in the dining room, there are mounted crossed a pair of double barrels. I looked closely at several when I was there and was surprised to see names like Purdey, Churchill and H&H. I asked the manager about them but he had no clue. Out of proof barrels? The elk is great.
