I have a question for you guys who are into ballistics....
I understand bullet types, expansion, performance results of the bullet itself. But I'm not deep into the velocities, pressures, energy, etc.
Testing data often comes from a 5" barrel. Let's say you carry a 3.5" or a 4" barrel. The shorter barrel should produce less velocity (maybe 50-75 fps) and energy with the same round. So you find a bullet that has good terminal characteristics, maybe a 9mm 124 gr Gold Dot. If both rounds are using the same bullet, would a +P loading in a shorter barrel offset the reduced velocity and basically achieve the same ballistics as the standard pressure load in a 5" barrel? Would using the +P be an effective method to achieve 5" barrel standard pressure performance in the shorter barrel?
Any downsides to a +P in a short barrel?
Thanks in advance for your thoughts and insights.
