M9A3 VS. FN9C VS. Oobleck

In this video I tested the Federal HST 124 gr. +P ammunition for penetration depth and overall devastation on impact with varying barrel lengths. The M9A3 has a barrel length of 5.2" and the FN9C has a barrel length of 3.6". I was surprised at the difference that Velocity made, and it might surprise you as well.

What test are you doing exactly?

My goodness, I just now am getting back to you. I was testing the difference in penetration through oobleck based on varying barrel length. So the M9 had a 5.5" barrel and the FN9C was a 3" barrel. I was surprised to find that the FN supplied more penetration than the M9 even though the shorter barrel would mean less velocity. I assumed that the higher velocity would equate to further penetration, but it meant that the bullet dumped energy at a faster rate.
