I think this stuff sounds too good to be true.
Standard pressure, low recoil, yet astounding ballistics results. Like, "Cavities produced are permanent cavities not temporary stretch cavities." I'm no expert on ballistics but this seems hard to believe. A 4" permanent cavity from a .32acp?
They're using bullet weights about 1/2 (or less) of standard bullet weights, which makes for increased velocity, but that alone would not account for such good performance, in my opinion.
I'll be interested to see what you think of this ammo if you actually try it.
