That's fine, it's based upon an opinion... and one that is based upon that your likely scenario is shooting thru metal, auto glass, etc. As far as walls, most are sheetrock, and I can poke a hole thru that with my finger... so that was just garbage. Many HP's may not make it thru glass, etc.... so that's not a big surprise.
I carry Hornandy in the mag in my gun, however, I also have 2 extra mags, and one is loaded with +P's, or +P+ FMJ's...... if I want penetration real quick, I know to drop the one and load the other. However, to me ... most SD situations will not be shooting thru glass, metal, etc.
You can always find something to argue against any ammo out there .... ammo is not made to for every situation type there is.
