- The full metal jacket bullet is suited to recreational shooting; it is not presented here as a hunting-specific load.
- The listed performance figures are tied to the stated 5.56 NATO load, so users should match it to firearms and use cases appropriate for that chambering.
- Brass casing is included in the product data, but no additional reloadability or lifecycle claims are provided here.
