The MTM RSS-50 ammo boxes are my preferred ammo boxes for my 6.5 Grendel & 6mm ARC ammo but there are a couple of other choices.
These Caldwell boxes are for 7.62x39 ammo. They work perfectly for 6.5 Grendel & 6mm ARC as well but higher in price.

These are also for 7.62x39 (22 PPC) but are made in China. The box hinge doesn't appear too durable. It may weaken & break with multiple openings & closings. I have some of these. They seem to be holding up so far.
