Looks to be a fairly ethical shot. Hopefully there was minimal suffering,hate to see a wounded fly bumbling through the neighborhood with a missing or non-funtional whatchamacallit.
I'd like to know that the remainder of the carcass was located and disposed of properly,as well. Reason being that if a complete pass-thru wasn't attained,the potential for lead poisoning to a scavenger might result. Worse yet,If this scavenger is from California,the chance of developing cancer becomes an ominous probability.
Lot of factors in play here. Please be safe and God Bless.
Mike.
