Will .243 Win rounds feed out of stagger feed long action magazine if I rebarrel a 30-06 I have? I currently swap back and forth between LA Barrels/calibers, but have never tried any of the SA rounds. I don't mind a little "tweaking" if I must, but honestly don't want to modify the magazine too much that I have to "tweak" them back when I go back to one of the LA calibers...
