I am sure thats the case, but apparently the post causes it to clog more consistently on certain clothing. I guess certain material gets in between the post and the rest of the bullet and it takes less to clog it, vs the intent of the post trying to keep material from getting in. Go figure, on ballistic gel tests it looks fine....unless you put different clothing in front of it.
Don't get me wrong, I have a mag full of hydrashoks in my 9mm because one of my dad's patience was a trainer at some facility for some federal agency, dea or fbi or something. And he gave a number of boxes to him as a present, and he passed along with wealth to me. EVENTUALLY I will shoot them and replace them with something else. Hydrashoks aren't necessarily a bad round, but there are better.
