Guns can get crazy expensive, and so can custom ammunition. When I used to race winter biathlon (ski/shoot), my rifle cost over $3000. Getting custom load ammo for a specific event (short notice, based on weather conditions for race day) was as much as $3/ea, and those were just teeny little .22 longs.

My father still has his 1968 Perazzi side by side competition breech loader. I can only imagine what that's worth now.
