It does have some value(like shooting a turkey neck to avoid lead-tainted meat), but it is a novelty or exotic round at the end of the day since it is far too powerful a round to be used for squirrel privateering. Also most woodland mammal cargo vessels haven’t use sails for decades before the bolo round cartridge became viable.

It may be a bit of a joke round, but it wouldn’t be very funny to find yourself at the business end of a derringer with one in the pipe.
