I'm sitting here building my next rifle in my head, and since it will be a hunting rifle I think I would like to go with a hinged floor plate. I know a detachable magazine may be easier all around but I really like the look of the plate better. So my question is other than the bottom metal, what is needed to convert from a fixed blind magazine to a hinged floor plate set up. I know I will have to inlet the stock but what about the internals? I would think they use a different magazine body, but I'm not sure, I have never owned a Savage with the hinged plate.
