My dad has a fairly old Model 94, he's had it since he was young. Based on the serial number we believe it was made in the 1930s. He doesn't shoot it very much because when he does, the primer gets pushed out of the case just a little bit. Not a whole lot, maybe the thickness of a fingernail, but he says because of this it's unsafe to shoot it. I've always been curious as to what might cause this, and if it truly makes it unsafe to shoot. If it matters it's chambered for 30-30 Win, and we're not sure if it has the original barrel on it or not. It's an octagonal barrel that looks to be a factory one, but we're not sure if it's the original one for this gun, looks like it may have been replaced at some point.
