I test out the Underwood Ammo 155gr Gold Dot 10mm load in the Clear Ballistics FBI gel block (calibrated to mfg specs) with 4 layers of denim with the Gen4 Glock 20 (factory spring).
Chrono Data (average):
1443 fps, 716 ft/lbs energy
155gr retained weight
.812 average expansion
As you'll see in the video, the bullet holds up pretty well with only minor deformation.
