First off let me start off by saying I would never recommend ANY!!! FMJ ammo for EDC/self defense. But if it’s all you had or could find readily available then I think the Winchester white Box 115 Grain FMJ “Hardball” would work the best. Test done using my M&P shield 9 3.1” barrel impact (1,095) FPS. Bullet ripped open the first 1gallon jug and tore through the second 1gallon jug with minimal damage. Then struck the 1/4” of solid plywood to represent hard bones inside thoracic cavity and completely passed through with a small hole exit no larger than entry. The projectile then fully penetrated the third and final 1gallon jug Kept going and deeply lodged in the wooden back stop. Penetration is whose guess but at least probably 30” or more The recovered bullet had no noticeable deformation. The second test I Placed a 2003 Ford Explorer car door about 10 feet away and sat a 1gallon jug directly behind the door. Impact velocity (1,103). The bullet struck and fully penetrated the steel car door and stopped inside the 1gallon jug behind it. The Projectile nose was significantly pushed in with a lot of noticeable deformation. This load also shot VERY ACCURATELY! From 5-35+ yards. So with all this being stated would any of you guys ever use has used 9mm FMJ Hardball or EDC/Personal defense???
