[QUOTE="Monkeygoat, post: 2414319, member: 112396"] MDT, just select the 3.56 option - perfect for Max/Mega: [URL]https://mdttac.com/300wm-mdt-metal-aics-magazine/[/URL] Great on the Prometheus - I see it now, I glossed over it because it says "338" lol So, really, you just need to decide what ballistics are worth to you...
