I just looked at my newest boxes of P9HST2, picked up in the last two months, and compared them to some older boxes I still had left. Definately can see the difference in the bullets. I'm not worried (yet), but why did Federal do this? Lot to lot variation is one thing, but this seems like a design change, or at least a major tweeking.
From what I have read here, the new version seems to be moving a little slower, and expanding a little less, but I don't know how this effects penetration, especially from my G26 barrel.
What did this "fix" that was "broken" before?
