My Hawkeye 223 loves the 65 gr Sierra GK, which isn't an expensive bullet, which makes it good for plinking and for critters. The Partition is great, but not cheap. And I've always had good luck with accuracy in the 223 and 220 using the Sierra 63 gr SMP. I've just switched over to the Nosler 64 gr BSB for pigs and other larger critters, though I haven't tried it out on a pig yet. Shoots good though in the 223 and, much to my surprise and joy, it stabilized and shot little groups in the 220 Swift.
