An early Stevens brochure states their tip-up rifles were chambered in 38-100 or 44-100 along with shotgun barrels. I've never seen reference to these calibers elsewhere. The diagram looks like a Ballard 38 ExL. I obtained one of the barrels and indeed a 38 ExL chambers. Has anyone seen data on the 38-100 or 44-100? I'm curious as to what the "100" stands for. Best, Dan
