Yes. I had a 60 ft basement/shop under my garage at one time not long ago. Great for air rifle, a bit noisy for .22 RF. You'll need a dedicated target backing with a hell of a lot more than magazines behind it.

As I recall, for a zero ricochet, bullet trapping .22 rifle backstop that, although heavy, is easy to move around, you will need approximately 9-10 inches in depth of "duct seal" as a target backing inside a 1/2" plywood cabinet. So you'd need to build or buy at least a 12" deep target cabinet.

There are also, steel angle plate backstops that you can make, or are commercially available.

Some have found good success with compacted rubber mulch... although I don't know the best depths for that.

Cheers... and get good hearing protection.
