cosh here - Hello to all! New 264 LBC-AR 20-inch barrel coming soon. Have enjoyed starting out 6.5mm caliber in bolt action (6.5x55 Swede). After reading various inspirations others have with this cartridge, it seemed natural to try 6.5mm in the AR platform. The .264 LBC looks good to go. Thank you for this forum and information shared here that helped me. Maybe I can contribute something when I learn more.
