Perhaps I don't know about all the technical stuff relating to SD, bullet penetration, and so on. I already admitted that I don't nor will I know as much as you do about bullets. But all the articles I read from gun writers about controlled-expanding bullets starting with the Partition and ending with solids, the ones that expand sooner and the most are unable to penetrate as deep as the ones that expand the least. Also, the A-Frame is talked about by the same writers as being superior to the Partition in relation to penetration.
