This could be a case of common names causing confusion.  In some parts of the world there is a wild prunus variety referred to as hackberry.  If that's what you have, I would suspect that its similar to choke cherry.  But that is purely a guess.  In the US, we have two kinds, sugarberry(southern Hackberry) and common Hackberry.  If you have one of these, they are nearly identical in properties and I treat it the same as Blackhawk does.  Josh
