We don't have, Prairie Dog's in my part of Idaho, just small "whistle Pig's" and Rock Marmots. I have a solid but, portable Bench, I start with, w/ 55 or, 60 gr. Bal Tip's, in my Adams Arms, 1-7 tw, "piston" driven, Giesele triggered, .223 Rem. for, the "close" shots. Working my way up to, the .22-250 Rem w/ 5-20X Scope, using 50-55 bal tip's or 52-53 gr. Sierra HP's, using, low Powder charge's of H-4895, to control recoil a bit. Next, I'll be on to my New, .243 Win with, the fantastic, 80 gr Sierra Blitz's or, 87 V- Maxes for, the longer stuff, OR, when, the WIND Blows, this year. The .223 Adam's is easily, Sub MOA and the two Bolts ( Sporter medium wt. Barrels ) are both, Sub 1/2 MOA Rifles. I like a bit of Variety when "playing" with whistle Pig's or, Rock Marmots and to keep my barrels "cool"! But for serious Coyote Huntin', I'll be taking the .243 Win., any Day now, as "loads" are getting, done. The Adam's AR, was bought, because Mrs Clinton, DOESN'T think, we should have, them ! Fun to shoot when, my grandson lets me, use it ! Lots of, "good choice's" posted, here ! Have fun !!
