My old man drilled it into me to not shoot them until mid-May, to give the babies a chance to be weaned from Mom before her getting shot. "Ya want more targets later in the summer or dontcha, kid?"
I just saw one creeping along the hill yesterday. I need to get a new barrel on the .220 Wilson arrow 700 I recently inherited, a 4300 FPS bullet ought to work perfectly to kill and clean in one shot haha.
