That was based on shootings from 25 years ago with a bullet designed for accurate potentially long-distance shots from a supressed MP5, not based on shootings using any of the bullets from 15 years ago to now. The people who have shot people with 147 grain HSTs and the other members of this generation have all been extremely happy. As in, the bullets did exactly what they were designed, advertised, intended, and expected to do. JHP design has really only had real growth since the early 90's, so to base your ammunition choices on bullets that were designed before manufacturers knew how to make a consistently performing JHP is foolish or uninformed. Since the internet is about ubiquitous, they're pretty much the same thing these days. The Winchester white box 147 hasn't been updated since it came out in the 80's, and it's never been a great expander, but with bullets there's no magic happening. It's a heavyweight bullet that doesn't expand as much as any of the newer offerings, which means it will give a lot of penetration. Think of it as a budget XTP, another mediocre expander that is known for great accuracy and penetration. Wanna kill these ads? We can help!
