Common Questions and FAQs

  • Will this ammo work in my AR-15?
    Yes, it is intended for 5.56×45 chambers and will feed and cycle reliably in AR-15 platforms and other firearms chambered for 5.56×45; always follow your firearm manufacturer’s guidance.
  • Is this ammunition reloadable?
    Yes, cases are brass and use Boxer primers, making them suitable for standard reloading practices.
  • Are the primers corrosive?
    No. This load uses noncorrosive primers, so normal cleaning routines after range use are sufficient.
  • Is this suitable for indoor range use?
    Yes, mechanically it is suitable, but it contains lead and is not lead-free; check your indoor range’s lead handling and ventilation policies before use.
  • Can I use this for self-defense?
    This is a full metal jacket training round optimized for target shooting; FMJ does not offer the terminal performance typically recommended for defensive applications.
  • Do you offer bulk case options and free shipping?
    This product is packaged in 20-round boxes and sold in 500-round cases for bulk buyers; bulk shipping offers are set by the retailer, so confirm current thresholds and free-shipping promotions with Target Sports USA.
