Today I finished shooting my last box of "old" Federal 230gr 45ACP Hydrashok which I purchased back in 1993 and open a "new" box of same ammo which I purchased about 6 months ago. I noticed the nose profile of the "new" ammo has changed to more round shape compared to the truncated shape of the "old" ammo. When did this change occure and has anybody notice any other difference between the "old" and the "new" Hydrashok design?
