What is your 243 going to be used for? If for varmint or deer hunting here in the states, any of the American bullets will work just as good, and a whole lot cheaper. If you must have a whiz bang hi-tech bullet try a Nosler Partition, Barns, the Win high tech bullets which I can't remember the name. I've kill a lot of game in the past 50 years, from rock chucks to elk and have never had a problem with the common bullets like Hornady, Speer or Seirra. But your milage may differ. Buy American, we need the money and jobs.
