Ditto.

I only tried 180's and 165's and just settled on the 165.

Since the 10mm is sorta like a .40S&W, I'll weigh in.

I carry either a Witness Classic 2 in 10mm or a Classic in .40S&W.

The 10mm rounds are Double Tap 135 gr. and the .40S&W are 165 gr. 165 gr. Hydra Shok.

135 corbons leave the most devastating wound channel. I posted test data somewhere a long time ago, but can't seem to find it. I read data and saw side by side results for three rounds of each, 9, .45, and .40 in different weights. It is not only the expansion, but the shockwave damage. The 135 corbons blew everything away.

Exactly what he said. but...

I use 135gr for spring/summer and 165gr for fall and 180gr for winter.

I'll use Federal HST as a first choice, Speer Gold Dots as a close second and Winchester PDX1s as a third choice. All of these rounds pass the FBIs service tests and are the only ones to score above 95% reliability in all test categories. Not that it matters that much, but its nice to know.
