Had to play into the trend here a bit!! ANyway I recently came across some 9mm critical defense, 50 grain leadless hollow points. Claiming 2000 fps, wither superior performance than other defense hp ammo on market. Anyone have any experience with these?? I thought they were normal hp, picked up the box, and it was so light I thought it was empty. Then read the info on box. Just curious if anyone has experience?
