So, the Springfield Trapdoor, the 1898 Krag, 1903 Springfield, 1898 Mauser, 1917 Enfield, and all the rest are not nor should be called sporting rifles either? They did not start that way, but were quickly converter into sporters. The M-1 carbine has been modified into a whole raft of wildcat sporter cartridges. Is that not a sporting rifle? You can buy a M-1 Garand in 459 Win mag if you have the money for it. I think that there is not a single sporting rifle that did not start out as a military rifle at its roots. The Henry rifle was a military weapon, the falling block single shot rifle started out as a military rifle. Perhaps the pum action rifle did not start as a military rifle, but I am probably wrong there. Your Model 70 was based largely on the 1898 Mauser design.
I am not defending the use of the term Modern Sporting Rifle, but I do feel that if a term like that make will make firearms more acceptable to the general populace, then that is to the good. I love old guns as much as anyone, but most people today cannot afford to buy into a pre-64 model 70. Have you seen the cost of a new model 94 lever action? Look at Marlin. I have a model 1895 that is now worth triple what I gave for it six years ago. Just saying. TD
