    Stuff that looks awesome there with 13-16 inches penetration and good expansion might not be that ideal. FBI dings 12-14 inch penetration even though considered "acceptable."

    The Deep rounds are moving in the right direction IMO.
    I thought expansion and penatration were both exaggerated in clear gel.

    This video is a good example. Check the description if pressed for time.

    The Lucky Gunner tests using short barreled pistols made it all the more likely for good rounds to fail or partially expand. The extra elasticity of the synthetic compound doesn't have the resistance of the organic pork stuff, resistance that would both initiate expansion and prevent deeper penetration.

    It makes shallow penetration quick expanding rounds look better than they are. Stuff like XTP that will perform well just about any time it hits a mammal, with enough penetration to get to the two shutdown buttons - brain and spine - look not so good.

    As it is the standard from the 80's with actual ordnance gel was correlated to torso hits not encountering bone, imagine clear gel. I want 16/18.5 inch minimum in ordnance/clear gel.

    Unfortunately, any results obtained in the Clear Ballistics stuff are not directly convertible to test results obtained in any other valid test medium because the variations in both expansion and penetration depths are non-linear in nature.
