Is all 147 grain 9mm subsonic?

[SMJayman]

Oh yeah, and if you reload, here's a sweet load that is pretty quiet even without a can. I've been meaning to try it through a suppressor but haven't had the chance yet:

9mm, 147gr Hornady XTP, 3.6gr Titegroup, CCI small pistol primer, 1.100" overall length, 10 shots:

968
957
980
970
981
984
972
966
979
986

SD 8
ES 26
AV 973
PF 143.031

We've never seen supersonic 9mm 147 gr standard pressure.

There are non +p loadings of 147 JHPs at over 1200 FPS published in the Vihta Vouri manual.

That velocity is not difficult to achieve in 9mm with a variety of slow burning powders, at standard pressures.

Granted, I am not aware of commercially loaded ammo at that velocity and bullet weight, although I do not use or suggest commercial ammo.

Nope, and pushing it through a 16" barrel can make it go faster.

I could be wrong, but I got the impression that he was referring to Factory loads.

Might I ask why you do not suggest commercial ammo?

I really dont see the need to make typical 147gr JHP's to be supersonic.



Left: 147gr Win JHP
4.6gr N350 COL=1,120-in
Winchester Primed Brass

Right: 147gr XTP
4.8gr 3N37 COL=1.120-in
Winchester Primed Brass

Both of them are subsonic. Both tested on water jugs (PET-1) with 6-inches in diameter. 147gr Win JHP recovered on third jug (less than 12-in penetration on calibrated gelatin), while the 147gr XTP was recovered on fourth jug.

Years ago I tested the 147gr XTP loaded with 5.0gr N350, and it fragmented on old books. You can only do so much within the limitations these bullets.
