Altor 9mm. The gun you have to have if you hate 9mm

Hornady 90gr xtp, usually around 30 cents or more loaded with 4.5gr of wst.
Vs
Berry's 100gr, about 20cents each with 3.5gr of nitro100nf. This is the one that looks like a star.
The 100gr Barry's is quieter and probably slower than the 90gr xtp.
I couldn't get a chronograph reading as it was dusk.

 

The 90gr xtp over 4.5gr of wst clocked in at 1,050.
The 100gr berry's HP over 3.5gr of nitro100nf did 940fps.
(These are 9mm loads)
That's making standard 380acp velocity assuming you have a little bit more barrel length and more, nearly double as much slower burning powders.
So either will keel.

Altor test, skip to 10:50

IDK what kinda ammo he was using, probably 115gr xtp by the looks of it.
