Let's not forget that some service caliber rounds achieve 1100+ fps. The 357 Sig, 40 S&W, 9mm and 10mm are all capable of achieving 1100-1400 fps within their respective caliber range. High velocity handgun rounds, say, 1100 fps+, should create more BPW than rounds in the 950-fps range. I think that we give weight too much consideration and not enough consideration to speed. We have the technology now to create bullets that are light and can with stand higher velocity and still hold together and penetrate. Handgun rounds may create a BPW that the body can handle, but it will cause a disruption to the system non-the-less.
Velocity needs to be around Mach 2 or better (2250 fps) to begin to see levels of BPW that are significantly in excess of what a body can handle and, thus, cause damage/disruption. Most SD handgun calibers fall way short of that mark. And even in rifle calibers, it's still about weight and
speed. The 180 grain loads for the 308 are very popular among those that hunt with the 308...and that is one of the heaviest
bullets for the 308. The 168 grain is one of the second heaviest for the 308, and it is the standard weight bullet for match ammo. When hunting dangerous game...what do hunters look for...they look for the biggest, heaviest bullets being pushed as fast as possible in a gun they can carry and shoot accurately.
