Maybe i should have worded my question differently, whats the most devestating, anti-personel round for the .233? I have a 12 guage, two pistols, two 22lrs, along with several other rifles. I have recently bought an AR-15 not thinking the world is coming to an end but because i have always wanted one. If im gonna have one in the house i want ammo that will be effective in it, im not too big on FMJ prjectiles.I not know this answer so i didnt mean to cause any in-fighting...
