If you kill one just keep calling, spaced multiples are common. I took two guys out in norther NV, one shooting a 22-250 and the other a 270, no cans we called three spaced over a few minutes, two killed and one came and sniffed one of the dead ones and bailed before a shot was taken. the first two killed were under 20 yards the fourth was about 70 yards when he died. keep calling.
I once killed one after he returned to the call after two misses. I could see him the whole time.
often after killing one a few minutes later one will come and sniff the dead one.
Nothing is set in stone with coyotes, one day the click of a safety spooks them the next day gunfire is meaningless.
All my hunting is days, no suppressors. Still debating with myself if I'll bother, not something high on my must have list.
