If you wanta factory load, there are plenty. Wichester white box 'Varmint Pack' (40 rounds 45gr Hollow point) is a good cheap effictive round if you aren't concerned with pelts. Black hills makes a bunch of different loads that are good. They make loads with 50 and 60 grain v-max's, and 40 and 50 grain Nosler BT's and a bunch of other hollow point loads. Pretty much anygood brand with a fast expanding bullet such as a ballistic tip or a hollow point. I shoot a hand load with 50 gr V-Max's and have shot the Winchester white boxes and they kill 'em pretty well.
