RE: remington sportser ????
Was the Winchester 88 ever offered in the 300Sav? (I want to say no, but honestly can't remember now!)
I can't find any evidence to say otherwise, but what about the remote possibility of Remington having built a few guns of such on a Browning patent like they did with the model 11? Browning had a falling out with Winchester in the early 1900s and Remington quickly came too John Moses with the hat in their hands.
Just a thought!
