This metal bodied AICS magazine feeds the 308 Winchester family of short action cartridges, 6.5 Creedmoor included, from a 10rd column. The AICS pattern is the standard for precision bolt guns, so it runs in MDT chassis systems and bottom metal from most chassis makers cut to the Accuracy International spec.10rds covers a full PRS stage or a long string at the steel range without a reload. Metal construction takes the abuse of getting slammed into a magwell on the clock and keeps presenting rounds at the same angle every time, which is what separates a magazine you trust from one you tolerate.
