Any time Im in the pasture with a rifle. Late May to mid June is the time for shooting p dog pups. I get plenty of shots within ranges for the 17 HM2 and 17 HMR rifles.
Some western states actually have a closed season..Apr 15-June 15.....to protect the young pups....this is usually on public lands...as in Utah..private farm property is not included..we start shooting second week of May.....pups are up & running.....
