Because, from what I read here on the Wire, many people who shoot .38's in a rifle chambered for .357, have to run a long OAL on the .38's to get them to feed reliably. The new Ruger Marlin is only chambered in .38/.357, so it is not a stretch to think that .38's shot in this rifle will need a similarly long OAL. If that isn't the case, that would be great. IMO (worth every penny you paid), it seems like a foolish mistake to produce a lever action rifle that, from the factory, will not hold 10 rounds of the cartridge that it is made to shoot. If you have some useful information on this subject, please share it.
