Wow, this is an oldtimers thread. I used those bullets back in 80s for self-defense loads in .38, .357 and .45. Soft swaged bullets but they had a gaping hollowpoint. He also sold a 146 grain "hydrashock" wadcutter with a post in the center of basically a reverse hollow-base wadcutter. I think he was originator of the design, as soon afterwards S&W picked up the bullet and was loading it in their branded ammo. When S&W went out of the ammo business and Federal bought their entire line, just about the only two things they kept were that Hydrashock load and the Nyclad line. Of course later Federal refined the Hydrashock into a jacketed bullet.
Great bullets. They were economical as well. No wonder he went out of business.
