Underwood 158 gr Gold Dot fired from 4" S&W Model 13 and 16" Rossi M92 carbine into calibrated 10% gelatin.

BB: 585.3 fps, 3.3"

Revolver results:

Impact velocity: 1,213 fps
Penetration: 20.9"
Retained weight: 158.1 gr
Max expansion: 0.612"
Min expansion: 0.494"

Carbine results:

Impact velocity: 1,967 fps
Penetration: 12.4"
Retained weight: 95.2 gr
Max expansion: 0.683"
Min expansion: 0.531"

I forgot to place denim but I have never seen a Gold Dot fail to expand except for very low velocity .38 spl. Denim might have increased penetration figures slightly.

thanks for all the gel testing you do.
this one really shows how bullets can penetrate further at lower velocities

Thanks for watching.

Got similar results with the Hornady Custom XTP 158gr. fired from my Rossi/Puma M92 20" barrel.

The bullet does better out of a revolver length barrel at a lower velocity.
