AI mag 300WM question

[R.Morehouse]

I have a build ready to go that has Badger bottom metal and 300WM A.I. mags. My question is what other rounds/calibers will fit in the 300WM AI mag without mod's to the mag. I have a 300RUM here already and have no problem with also having the WM, I was just wanting to know what other options I may have before I buy the barrel.........Thank's

Unfortunately, you won't be able to use any RUM size cases in the 300 WM AI mag. It will, however, function with WSM, and other standard magnum cartidges ie: 7mm RM, 338 WM

If you intend to use it to feed a WBY mag you will need to modify it.
