I have both an 1897 and an 1892 that I like to shoot, but I can only use standard velocity shells and they seem to be tough to find. However, I have thousands of high velocity fodder at hand for my 10/22 and others. Im wondering if I could have a 39A bolt fitted to either the 92 or 97 to allow me to shoot high velocity ammunition? I guess I could just shoot my 39D or 39A, but I prefer the feel of the older rifles and would like to shoot them even more. Or is the bolt not the only limiting factor in sticking strictly to standard velocity rounds?
