I've only had my 1-9 CZ for 4 years, but to date the stars for accuracy are: 40gr Varmageddon and Blitz King, 53gr Varmageddon, 65gr Game King and 69gr Match King. Several others are plenty accurate for a 250 yd coyote (don't have many groundhogs here). The real star for less-than-deer looks to be the 53gr. I have several others to wring out including Ingwe's favorite 63gr Sierra and 75gr Hornady BTHP. All in all, I'm finding this to be a very versatile rifle.
