I don't own a Pro 300, so I don't know what others get, but I don't think that's a cause of concern. The boiler is 325mL and you use about 60mL to brew (also assume the brew is set to 200F and the reservoir is at 70F) then the temperature after brewing would be:
(265 * 200 + 60 * 70 ) / 325 = 176 F
With a little bit of heating during the shot, and not sure where the brew boiler temperature is measured, then 185 F seems pretty reasonable.
