I'm sure there's gotta be guys out there having as much trouble with these as I am. My first was broken out of the box. The replacement had one of the three bottom tabs broken (back one). I bought another one and have since glued the bottoms in. The rear metal tabs at the top don't grab the ledge up in there and hang out just enough that the bolt doesn't catch the shell for loading. I've bent the tabs out a bit but they just bend back. An attempt to try an bend out the top bent over part so it could grab the ledge better failed with it snapping off. I have to have my finger pressing up on the rear of the mag for it to pick up the bullet.
I sure hope savage is aware of this and is coming up with a solution. I did notice these mags seem to all be on back order now everywhere so maybe they are working on a fix.
