I think this question gets a wide range of answers because so many variables.. Called in coyotes in Texas compared to guys jumping them with trucks in North Dakota are pretty different performance needs. Size of coyote, average shot distance, speed on impact and shot placement leads to vastly different results. This question is what got me reloading to begin with. People with far more dead coyotes than me steered me towards 60gr vmax , Sierra 55 gr soft point and Speer 1035 52 gr hollow point. None of these bullets have not worked for me on called Midwest/Western coyotes with good killing and generally easy on fur. I also really like that Sierra in.22/250 for when I need more reach. I had from great to horrible results with other weights of vmax , sx and Btips so for my purposes I no longer use really fragile varmit bullets on coyotes. You will find most bullets from 223 will kill coyotes most of the time but everyone’s situations and end results can vary.
