A few years back in northeastern kansas near the nebraska border. In our huntin party we had 4 guys a 243 and 2 .223's and 1 22-250 after 3 days our grand total was 756 Prairie dogs and 12 coyotes. I personally shot 198 prarie dogs and 1 coyote with 52 grain speer HPBT handloads from My Rem M700 VLS in .223. But only been back there once since then and there were hardly any Prairie dogs around I shot only 12 that trip they said the population declined do to drought but I think we just shot them all the year before.
