Oath Tango Cartridges

I only saw a picture in this forum which showed a Oath Halo cartridge but was noted as a Tango, on a tread not on the subject. So I wanted to do a tread on the Oath Tango.
Below is from Oath’s Web-site:
“The entire Tango™ line consists of all precision machined Lead Free defense rounds that deliver the most reliable and unique penetration characteristics of any special purpose ammunition. ​The Tango™ series is the first defense projectile that delivers optimal energy transfer upon penetration. ​Watch our performance demonstration videos to learn more. ​ O​nce you fire the Tango™ you will welcome the reassurance ​it brings by loading it into your weapons.”
My Ideas on the cartridge:
These very unique projectiles are copper hollow points, with extremely deep pockets, or slits in the
sides with a copper or brass top bonded on top of the projectile. This would give maximum expansion on impact and increase
good cycling in the firearm.
Below a few pictures, showing 380 Auto,9mm Luger, 38 Special, 357 Magnum, 40 S&W, 10mm Auto, 45 Auto
