I have to honestly tell you that I had two 375 Rugers that would not do that so I am envious.
The Alaskan when the first round was fired and extracted would pop the second round up and out of the magazine rendering the rifle out of action.
My African would do the opposite and would bind the second round jamming the gun,
To this date I have never heard of another CGNer having any similar issues with those models, quite the contrary everyone seems satisfied with their Rugers.
As a point of interest I am playing with a Shilen bolt action in 340 Weatherby that feeds and cycles 375 Ruger cartridges like a dream...
