I have had this box of ammo for some time now and now that I decide to test them it looks like it’s been discontinued. Part of the reason for waiting was trying to figure out how to evaluate them. Trying to evaluate them on the permanent wound damage in the gel is subjective and open to interpretation.
From the Sig P229, I got a five-shot average velocity of 1411fps with a high of 1421 and a low of 1403fps.
With the Kahr, the five-shot average was 1323fps with a high of 1331 and a low of 1316fps. The recoil in both pistols was very mild.
From the Sig, the first round had a velocity of1420fps and penetrated to16.75 inches. The second round hit the block at 1416fps and went to a depth of 16 inches. The bullets had a recovered weight of 82.1 and 82.4 grains with no expansion. Both bullets were recovered base forward.
In the heavy clothing covered gel, the first round’s velocity was 1452fps and its penetration was 16.5 inches. The second round had a velocity of 1436fps and penetrated to 15.75 inches. Recovered weight was 82.1 and 82.7 grains and no expansion. Both bullets were recovered base forward.
Out of the Kahr, the first round’s velocity was 1309fps and it penetrated to a depth of 15.5 inches. Round two also penetrated to 15.5 inches with a velocity of 1331fps. Both bullets were recovered base forward with a weight of 82.6 and 82 grains, no expansion.
I tried getting some decent pics of the tracks in the gel but as normal they are not so great. But they definitely showed much more permanent damage then ball. Most likely from tumbling. Not as much as you see with good hollow points but more then I expected.
