I acquired the impression from reading things over a period of years at hollow point round will typically mushroom out quicker and penetrate less when the velocity is increased. I was at Lucky Gunner website and read over the tests they did with various calibers and brands of ammo. However, the pistols they typically used had barrels a little on the short side. With a longer barrel there is more velocity.
An example of the above, though not related to the Lucky Gunner tests, is the old-school 9mm Federal brand 115 grain hollow point at standard and +P+ velocities. With the standard velocity one, penetration went through the whole ballistic gel block and didn't expand. OTOH, the same bullet pushed at +P+ velocities penetrated much less and mushroomed out a lot.
Sticking with 9mm and .45, which hollow points are less likely to mushroom out quickly and penetrate more with a longer barrel and higher velocity? OTOH, which hollow points are more likely to mushroom out quickly and penetrate less?
