    because traditionally they were for shooting varmits,spin a varmit projectile too fast and it doesnt make it to the target,centrifugal force rips it apart in mid air,slow down the twist and you slow down that centrifugal force...somewhere in vicinaty of 180,000 rpm for a std load 1;12twist doing 3000fps
    Im told the extra speed will allow SLIGHTLY heavier projectiles to stabalise but its a case of try n see...

    I hear you but that was back in the day.
    Not now. I suppose if they didn't do the heavier military ammo back in the day 223 might not have either.
