I shot the following ammo today. The subsonics are very quiet, even unsuppressed. I had one failure to eject in the lowest gas setting. I increased the grass to the high setting and it ran smooth and seemleasly Winchester Ammunition, Super Suppressed, 300 Blackout, 200 Grain, Open Tip, 20 Rounds Hornady Frontier 300 Blackout, 125 Gr FMJ, 40 Rounds SELLIER & BELLOT 300 BLACKOUT, 200GR, SUBSONIC, 11 Rounds Sellier & Bellot 300 Blackout, 147GR FMJ, 20 Rounds The supersonic rounds had quite a bit of punch as expected. They were much louder but still not extremely concussive like the 556 round. I really enjoyed shooting the subsonic rounds, I'm going to try some defense subsonic rounds this week and decide on one to keep by the bedside. I'll be shooting this gun with subsonic moving forward unless outdoors. The smoothest shooting was the s&b 200 grain subsonic, I zeroed in at 15 yd and it was relatively accurate. My spreads were roughly 1.5 to 2 in.
