Basement at work has about 60 feet ot unobstructed isle with a backwall of concrete foundation. Ventalation will be squirrel cage draw fan aimed towards the elevator shaft. Range use will be before or after store hours.
Want to make a backstop/ sand trap. Safety is #1 here. My idea is a piece of steel, maybe 36x60 inches,suspended ,attached to the ceiling at an angle down into abox of sand, maybe 12 inches deep.
Many thanks if someone can give advice on how to and specifics on sizes, thickness, angle etc..
P.S. handguns only
