Why I can understand your disapointment , I dont think you should bash the gun for not being abel to shoot a COL [case overall length] cartrage, that is over the spec's . If thats what was intended , you probably would have been better of with a single shot like the #one . I believe all magizine feed rifles will have this same problem , and it will be exadurated with the super short , super fat cartrages , like the 243wssm .
