Youtube tests rarely (almost never) include shooting through intermediate barriers. Popping a row of milk jugs with a bullet is about as ideal as it gets for bullet performance.
Personally, I've watched with hope, a LOT of the .38 Special +p and non+p hollow point ammo tests ... always coming back to the 158 grain LSWC - no hollow point to fail, velocity is good, and penetration is good, too.
What is the difference in the wound cavity between a LSWCHP that fails to expand and a SWC that will never expand? Within the thickness of a human, nothing.
