In a 9mm carbine with 16" barrel, what FMJ round would penetrate the furthest in ballistic gelatin? 115, 124 or 147? I am guessing 124.
Also, overpressure ammunition (+P, +P+ etc) penetrates less with Hollow Points then standard due to the faster FPS, however overpressure (+P, +P+) FMJ should penetrate further then standard FMJ ball.
I don't have much experience with gel, so I'm asking the guys who have done plenty of testing what they would think. I know out of a pistol 147 doesn't go as far as a 124, but the carbine's barrel can accelerate that, along with the help of a hot FMJ load.
