This should probably be called “friends don’t let friends carry a 25”. I was able to borrow an FN Baby Browning to test some .25 Auto. This gun is little and I mean little. I don’t see how you could make a pistol any smaller and still have any practicality at all. The size and almost non-existence sights make it very hard to shoot well.
I got a five shot average velocity of 767fps with a high of 791fps and a low of 752fps.
The first round in the bare gel had a velocity of725fps and penetrated to 12.25 inches. There was not expansion and the recovered weight was 35.1 grains. The second round’s velocity was 777fps and it penetrated to 9.75 inches. The hollow point deformed but did not expand over its original size. The recovered weight was 35 grains.
When shot in the gel-covered with the heavy clothing the first round had a velocity of 801fps and it penetrated to 12.25 inches. There was not expansion and the recovered weight was 35.1 grains. The last round penetrated to 9.5 inches with no expansion. Its recovered weight was 35.1 grains also and there was not a velocity reading.
I’m going to try and wrap this up tomorrow and return the pistol. Next will be the Hornady 35gr XTP and then some Fiocchi FMJ.
