I like the STs. Pretty bullets. But todays STs aren't like those of yesteryear. Don't think it will make a hunting round out of the 9mm. May add 80 FPS to velocity. I didn't use STs but used Rem 230 gr Golden Saber HPs on an elk...short range...under 50 ft. Left side boiler room just pop pop pop. cover 'em with your hand...all under the skin right side took 3 steps. Even an antelope should get heavy handgun bullets. I have one of the adapters for 32 ACP for 30-30..I shot a PD with a Win 32 ACP Silvertip at about 10 yards. Pretty anemic....and I happen to have 5 or 6 boxes of them. I have shot some of them..fairly accurate but somewhat underwhelming as far as terminal performance. I do like the 115 Gold Dot bullets in the 9mm. I carry them in my Sig 365
