I had a 35 Newton ( First Model) that had a crack/busted stock that was epoxied back together. I fired it with a limited number of full-house loads and it held. Looking back, that was probably a foolish thing to do. If your rifle were mine, I might load cartridges duplicating 35 Remington ballistics to lessen the liklihood that you'll crack a valuable stock. There are probably less than fifty First Model Newtons ( Model 1916 nowadays) 35 Newtons out there. Bruce Jennings ( he's been gone ten years this month) once wrote me that he could account for only eighteen in all his years of keeping track.
