Do you have any pics of this? I'd really like to see it as it sounds pretty interesting.
No pics, but anyone with a few brain cells to rub together should be able to figure it out. Go to a trucking company or a big truck tire shop and scavenge up about a dozen worn out tires. They'll probably give them to you. Build a wood or metal rack that puts the hole in the tire at shooting bench height and stand the tires up side by side. Drill holes in the sidewalls and bolt them together with fender washers so you create a long tube.to shoot through. The air chambers of the tires create a series of baffles to absorb the pressure waves that cause the sound to travel. It's just like a suppressor on steroids. A side benefit is that it creates a glare-proof tunnel so you can shoot with the sun behind the target- - - -no glare that wipes out the scope picture.

Won't work to solve her problem. The loudest noise comes from the sonic boom of the bullet. A 50BMG is still supersonic after it leaves the tires.
And it won't solve the ricochet problem down range. I'm no expert but I've been associated with two ranges that had ricochet problems from rifle bullets off the berm. I don't think the range inthe photo is safe.
Get range safety guidlines from the NRA and then file an injunction. Shouldn't matter if there is a Florida statute. The issue is endangering lives, not following some ordnance.
