I think you would probably get a smoke colored calf because of the Charolais influence. I have had a Charolais cross bull on a Black Angus cow and it was a smoke color. But if you bred to a Red Angus it will most likely come out like a cream sickle color!
I haven't used Milkman yet but have used Alias an so far have gotten all black calves out of him an black cow's . I used tinman on black cow an got a smoke calf an he is a son of Alias. Jamie The naughty pine bull seem's to sire more red ones on Char cow then Carnac or Alias.
