This was really just for fun, and to see how far I could push this round. The rifle was an AAC Micro Seven chambered in 300 blackout. It has a 16 inch barrel, and mounted on top was a Leupold Mark 6 3-18x44mm scope in a Spuhr 4001 Mount. It was suppressed by an AAC Cyclone .30 caliber silencer. I was shooting 125gr Nosler BT bullets at 2300 FPS. To get my dope I used my Kestrel 4500 NV with Applied Ballistics using Bryan Litz custom drag curves.
