The naming conventions don’t follow one system, which is probably why it feels random. BLK does seem tied to the suppressed-SBR angle, but ARC and PRC are just Hornady marketing families, and Creedmoor’s a place name—so there’s no unified logic to it.

You’re onto something with the naming conventions feeling random. The BLK designation does tie into its design for subsonic loads and versatility, especially in shorter barrels.
As for ARC and PRC, they are indeed marketing terms from Hornady that don’t follow a strict naming logic. Creedmoor, being a place name, adds to the mix of confusion.
It’s a bit of a patchwork, reflecting the evolution of these cartridges rather than a unified system. If you’re curious about how these naming conventions affect performance or application, let me know!
