I'm wondering whether maybe the choke on the newer Browning was opened to something closer to the "standard" mod constriction for a 16ga. O'Connor's "Shotgun Book" (1965) shows Browning's mod constriction at .025--but even that is tight compared to what he lists for Remington and Winchester in the same chart (.017 and .016, respectively). My most recent Sweet 16 is a 1967 gun marked mod; measures .023.
