Berger Bullets 31021: The 6.5 Creedmoor 130 GR Berger AR Hybrid OTM round was a purpose built round, designed to be the highest performing round out of a AR platform gas gun chambered to 6.5 Creedmoor. No other bullet compares to the AR Hybrid when it comes to performance out of this platform, and all it will take is trying it once for you to see the difference. Luckily for bolt gun shooters, this round performs just as great even when single fed, as its bullet is made to function well out of all 6.5 Creedmoor chambers.
