Corrugated stell culvert prices :
12" is about $10/ft.
36" is about $30/ft.
It goes up at a faster rate beyond 36" due to 16 ga. is no longer strong enough. So even a 36" shooting tube of 50 yards would cost $4500 for the culvert alone. I'm guessing that is only about 1/2 of the total cost.
Trenching, water-proofing, sound dampening, target retrieving/replacing equipment, ventilation fans/piping and lighting would add several thousand at least.
Nothing compare to the $200 per foot if you go 8'x8' 8" thick concrete and a gravel floor.
