The Australia Big Game Rifle competitions using the Blaser BBF97 in double rifle barrels in 9.3x74R and the Sako Quad 22LR. Also a fallow deer target at 100m with a gong in the heart region offhand with the BBF97. Sure makes a ding when you hit it.
Plus a few clay pigeons using the Chippa Triple Crown 20G and Shotkam Gen 4 with 24 gram #7.5 loads. That third barrel comes in handy.
