Trouble with 10mm was, its lack of popularity as a police gun greatly limited field experience with it. The 180 grain FBI load essentially mimicked .40 S&W in 180 grain. The Silvertip worked great but as you've found, is very hard to find. Anything in the 155-165 grain, 1300 foot-seconds range with a proven hollow point design should get the job done.
