Range Report -
black hills 77gr OTM kind of mid. Extremely similar velocity to the (old) AAC 77gr OTM but it did group well, around 1.5 MOA best 5 round group. Federal gold medal went at an outright leisurely pace basically 7.62x39 tier but admittedly pretty accurate and consistent. Best 5 round was about 1.25 MOA. Probably would save the gold medal stuff for 18"+ but would buy more if you wanted super accurate ammo.
Black hills don't know if I see the hype. For the price you can get NAS3 which while not groundbreaking is objectively better.
