I've been seeing "Lightning Ammo" brand .224 projectiles around lately, but there is terribly little info on their quality, save for one guy on YT who relates a very bad experience with them. Even the vendors selling them online don't seem to have any reviews of the product, so I probably don't even need to ask the question. That said, I'm an optimist at heart and would love to hear if anyone has actually loaded any of these personally and how it went.
