Which box/follower for the 6x47 Lapua?

[distantfoe]

I've got a Predator action on the way and would like to shoot 105 bergers. Was hoping to cycle them through the magazine, any ideas or suggestions. Thought a centerline feeding box might eliminate any timing problems?

Thanks

I've got a Stiller being made up for me too. I'm using Williams lower metal and a Wyatt magazine box. I expect the gunsmith will just use a standard Rem 700 follower.
