Lower bloom means that the crosshairs have less expansion than normal but they still expand with sustained fire. However, if the weapon didn't have crosshair expansion originally, then there will never be crosshair expansion, as for example in tje case of the VBI SMG and FRC Assault Carbine.
The base accuracy of a VBI Assault Rifle is superior to that of a VBI SMG by a large amount. As such, it takes quite a while before the VBI Assault Rifle's accuracy becomes inferior to that of a VBI SMG.
