Very interesting tech.

Only crushed glass in the 12 gauge is maybe more interesting. (Close work).
A surgeon of my acquaintance convinced me to stock/carry the Black Talon. Black Talon are less likely than most hollowed points to ‘choke’ on down jackets, nylon, and denim.
Hard to stockpile now though...... $85.00 per box in .357 at a recent gun show. Managed 19 boxes at $12.50 before the press attacked.
In South Minneapolis leather 50s style leather jackets are the norm for the hoods, that and sub zero temperatures, and layering, really woke me up to clothing issues and bullets.
I think that many of us who grow up in warm and hot climates, don't give enough thought to penetration and seasonal loads for carry.
