You can have your very own, and for less than you might think. A basic bullet trap setup will run you in the neighborhood of $10k. If you are looking for more higher end you can opt for multiple ranges that can support high powered rifles for a
few $100k. A more middle of the road solution will set you back a mere 60K.
Safety and sound proofing are key and a typical box-in-a-box design is the preferred method when constructing a home range. Create a box within a box design by using 6 inch poured concrete or 8 inch cinder blocks filled with concrete. Either method
helps to ensure the spent rounds stay put.
Next is overhead protection, a concrete ceiling will do the trick, add in some acoustic dura panels to hold in the sound and you are almost ready to fire away.
Keeping the range properly ventilated is important for any indoor range. You want to draw the air downrange and make sure the range ventilation is not connected to the rest of the house. The last thing you want is lead dust and other particles flying
around the living room.
Retrofitting your home for an indoor range can be done if you have the space for it, but the easiest and most cost effective way is to have it installed as you are building your house. You shouldn't have to look far to find a local builder to tackle it
Consult your local experts before you start building an indoor range and make sure you obtain any local permits you need before you begin any work.
There are several companies that will build a custom range for you and ship it right to you for installation. Check out this video for a great resource.
