TonyJoey,
No doubt, that should have taken out that Mossie. I can post an image of a real Mossie that took two or three 30mm rounds from an Me262, but you hit far harder than that.
Your evaluation of the .50 cals is off though, the Mossie is very tough and I routinely get peppered with .50 cal fire for no effect on my Mossie.
