Got a Savage long action DRAKE / MDT chassis on the way, now the question is which magazine to get...

Have a mcGowan 270 win target barrel, and a 6.5 creedmoor Shilen target barrel, and like to get a magazine for the chassis that will handle both. I currently have the 6.5 mounted on a long action and managed to make it feed the 6.5 by a lot of tweaking the metal feed lips (out of the factory long action mag)

Anybody knows which of the following mags has the longer feed lips , MDT or the Magpul Pmags? (or perhaps another one?)

Thanks!
