Brunswick used to have the drilling sheets online for public access, and earlier sheets also had the complete current line-up with specs and "reaction numbers" attached (and if I remember correctly even the reaction chart sheet was included, long ago...).
You might check the retired ball area, but I suppose that it has become hard to find more recent reaction charts.
