Well, I was in a hurry and I screwed this test up a bit. I forgot to bring my camera and my BB gun so I didn't produce a video or get a calibration figure immediately before testing. I did calibrate it at home a few days before the test but technically it's supposed to be done immediately before the test. I still thought it would be worth sharing the results. I'll repeat the JSP test and do it properly since I wanted to see the JSP from a carbine anyway.


125 gr GDHP over 14.0gr AA9 from carbine:

Impact velocity: 1,904 fps
Penetration: 10.7"
Retained weight: 50.8gr
Max expansion: 0.567"
Min expansion: 0.443"


158gr Speer JSP over 13.0 gr AA9 from revolver:

Impact velocity:1,108 fps
Penetration: 17.1"
Retained weight: 157.4 gr
Max expansion: 0.655"
Min expansion: 0.450"

At that velocity I'm surprised the 125 penetrated even that far.

Need to try the 158 in the rifle and 125 in the revo.

I did do the 125 gr in the revolver (below) and I will do the 158 gr in the rifle. I'm looking for a load that performs adequately in both. I expected the 125 gr wouldn't do all that well but I wanted to try anyway. I have high hopes for the 158 gr JSP and I also think that Remington's 180 gr SJHP ought to do well.
