Something new for me; never seen it before. I got a box (20) of
Liberty Ammo 78gr .45cal ACP HPs (1900fps) from my cousin on Saturday, and it's some amazing PD loads. Loud, heavily fragmenting at 2" in wound channel, and a small metal 'ashtray' disc spins-off all over the place inside the ballistic gelatin, creating a massive wound. Very small recoil. Rips good, tight groups in paper to 15-20yds.
