I believe you may be confusing some with how your asking the question, Federal hst generation 2, the t in HST means two as in Hydra-Shock Two, there is no second gereration beyond this. You may confirm this at Federals LE downloads that will confrim Part numbers here is the address: http://le.atk.com/Interior.asp?section=1&page=pages/downloads.asp The 1,2, or 3 at the end of their part number denotes bullet grains. I have got HST 40cal. at www.ammoman.com and all others at www.streichers.com, you would think someone would be selling bulk at www.gunbrokers.com, but I only see Winchester Ranger SXT with would be my second choice. Good luck and save some HST for me...lol.
