This weekend I am going to run an experiment. I am going to shoot various rounds through a Ruger P89 pistol and a Marlin Camp Carbine in order to assess how much, on average, firing a 9mm round through a longer barrel increases velocity. I have bullets in 115, 124, 135, and 147 grain weights.
Here is my issue - the Camp Carbine has Micro-Groove rifling whereas the P89 has standard rifling. This kinda makes for apples-to-oranges comparison of velocity as the difference may be rifling related instead of barrel length related.
My question to you is: is there anyone in the Gainesville, FL area with another type of 9mm carbine (Kel-Tec, Ruger, etc.) who might be willing to meet with me at the local range for doing this test? I intend to post all results here in TFL complete with statistical analysis and energy calculations. I will cover the range and ammo costs. Please e-mail me if interested.
