Do 6 ARC and 6.5 Grendel use the same magazines?
As the title suggests, can you reliably use a 6.5 Grendel mag for 6 ARC?

Duramag makes one magazine for both calibers, FWTW.

If I correctly understand the cartridge design specs, both have the same parent case. The case for the 6 ARC is about .03" shorter and the shoulder is moved to the rear by about the same. A magazine which works well for one should work well for the other.
