They went back to the traditional "Ballard" cut, on the 45/70, because the cowboy shooters were bitchin' and raisin' hell. But the 444 ain't Cowboy-legal, so they might not have changed it.
But then again, they changed it on their 44 magnums rifles, and it would make sense to use the same barrel stock. So maybe they did.
I guess that means, "I don't know".
