I am SURE this is well-trodden territory but what are y'alls thoughts on 300 BLK subsonic battle zeros. I have a DD PDW and I have zeroed it about dead on at 25 and it lands about 3 inches low at 100. Seems reasonably useful. But is there any good standard zero ideas out there I have ZERO interest in supersonic performance. I have this one strictly set up to shoot suppressed subsonic. Any thoughts?
