About fifteen years ago I was offered a box of 1000 158 grain Fed Hydrashoks at a very attractive price. I bought them.
Loaded in .357 mag with recommended powder charges and producing around 1350 fps (chrono'd) they were dismal failures in the expansion category. Accurate, yes. A friend loaded a few to top velocity, shot a deer and got basically a straight hole through the lungs. Deer died but it took a while.
Not criticizing the brand or the style but I think I know why mine were so cheap. Wouldn't expand reliably in water, wet newsprint, mud, sand or anything else. I gave the rest to another buddy who loads for a 92 Win replica rifle. He gets them up around 1750 and says he gets good expansion but I have not seen any examples.
Factory stuff, I've heard, does quite well and I wouldn't be afraid to try it. As for me now, I use Sierra stuff and have been well pleased.
Again, I think what I got was factory seconds that didn't meet spec.
