Paintball?
Think Skeet Shooting.
When I got serious into tournament paintball...I had $1000 in my marker(gun), $100 in the mask and ammo belt, and blew an easy $100 per tournament on paint at $50 a 2000 round case. Not counting entry fees, gas, etc.
I know skeet shooting can be high. I live not far from the venue used during the 96 olympics and a bunch of duck, quail hunters.
