PDW / CQB Options

Has anyone done any research on their own or read any good articles on this subject?

Doing an informal comparison between a 125 grain subsonic .300 B.O. @ 1000 fps versus a 124 grain 9mm +P at 1300 fps, both out of 10.5 inch AR pistols.

I know that the B.O. was designed as an "upgrade", so to speak, over a subsonic/suppressed 9mm sub gun for longer range/better down range ballistics.

But what if you were not talking about running either of them suppressed? How much would the increased muzzle blast of the .300 weigh in on the equation, then?

Subsonic 300 Blk is usually in the 200-220 gr range, 120 gr bullets will be supersonic.

300 isn't sub until you get into 200 grain range. Pretty much a 45acp at that point. I played with it some and wasn't impressed. Poor ballistics, added expense, and a time burglar to load for.

I'll take a 9 mil any day especially out of a 10" pipe.

125gr SST over 20gr Lil Gun was my preferred load when I had a 300 BLK. Velocity was approaching 2400 fps out of my Ruger American Ranch. I guess you could load it down using Trail Boss or a similar powder, but you would need to use a cast lead or some sort of bullet specifically designed to expand at those velocities.

If the point of the experiment is to compare it to a 124gr 9mm, I think you would really be handicapping the 300 BLK by running a 125gr bullet at that speed.
