    Think about what the effects of a pointed nose profile on drag, penetration depth, temporary stretch cavity, as well as permanent cavity?

    What about the folding back the gilded metal jacket and how does that interact with the TC, PC, Pen, etc...?

    For those of us not as ballistically knowledgeable, could you expand on that?

    Sorry for the pun ... not totally, maybe just a little bit. ;-)

    From post #16

    "The erect post propelled tissue out of the path of the expanded bullet, reducing the amount of tissue that was contacted and crushed as the bullet penetrated. As a result, the bullet produced a narrower, but deeper, permanent cavity compared to conventional JHP bullets of the same caliber, weight, velocity and expanded diameter."

    ...so you're saying it needs some nice sharp talons to cut a wider wound cavity without adding enough drag to under penetrate?

    Scroll down this FirearmsTactical.com article for more information on Winchester Ranger Talon.

    https://web.archive.org/web/20140109...tm#Black-Talon

    "Upon impact with flesh Ranger Talon performs identical to conventional hollowpoint bullets. However, as it penetrates and slows it does not suffer a decrease in effective bullet diameter. This is because tissue that stretches and flows around the smooth shoulder of the mushroom-shaped lead core comes into contact with the sharp copper jacket claws and is lacerated.

    These lacerations contribute little to overall wound severity."

    380 Auto is too constrained by size and pressure limitations to equally benefit from modern bullet design that has improved 9x19mm terminal performance.
