I have sporter weight 22-250 Rem and 220 Swift which now are only used for limited shooting coyote hunting
. The barrels of the two rifles heated up fast when shooting prairie dogs. I live in prairie dog country and have two varmint heavy barrel 223 Rem rifles but since getting a .204 Ruger target varmint rifle I dont use them very much. If I were to do a lot of hunting on foot I would get a sporter weight 204 rifle. I like the lower recoil of the 204 when there is a lot of shooting at prairie dogs.
