Today I received some boxes of 9mm and .45acp “Halo Point” hollow point ammo (they are temporarily out of .40S&W which they also advertise). It is from Liberty Ammunition out of Clearwater, FL, and they market this ammo as a lead-free civilian-legal premium defense load. Their military version is apparently an AP type for defeating Kevlar, but they weren’t forthcoming with too many details when I asked them about that version. This civilian Halo ammo looks to be a new & unique projectile. The grain weights are all ones that I have not seen before, and so they are not merely nickeled versions of an existing SCHP bullet. They look to be Nickel-bronze (my guess), but the Liberty website mentions silver. It is definitely some sort of use of tin, aluminum, nickel or bronze going on with these, and the bullets do exhibit a moderate attraction to a very strong magnet.
Note how on the back of the box they show a ballistics-gel photo, supposedly of how their Halo bullets are superior to typical FMJ ball. The low recoil and relatively high velocity, coupled with the projectile fragmentation do make for an impressive sounding load, but I have not tried these on anything:
