I always hear people in the savage world talking about having a model 11 staggerfed or a model 10 centerfed. I guess my main question is are all the actions from different models interchangeable as long as you have the correct mag fed components? I have been wondering this for a while but can't seem to stumble across the right history lesson. Also, are all the models made now centerfed? No matter if its a stevens, model 10, 11, 12 this is how I took a article I was reading the other day but the wording was somewhat misleading. Are the action screw spacing and the specs all the same? Thanks in advance guys
