In my .223, I have the best results with 40 grain moly coated V-Max from Hornady. I also have good results with the 50 grain V-Max. Both drop coyotes dead, but fragment so that there is no apparent exit wound. They are also very forgiving. Even with poor shot placement ever now and then, the end result is still a dead coyote. My gun won't shoot the nice little clover leaf at 100 with larger bullets, so I have never used them that much. When I first got my gun, I sighted it in and then shot a box of each of seven types of ammo. Four 3 shot rounds at paper, and the remainder at varmints. From my gun, the V-Max shot the best on paper and made the cleanest kills in the field. Guns and Ammo got the same results in a test they did comparing varmint guns and ammo on paper. Their Browning liked the same ammo mine did. But remember, this is my gun, and yours may be different. With the exception of FMJ, I would shoot a few of each on paper and then use the one your gun shoots best.
