Phillips had interim name suppression, which lapsed this morning.
In an affidavit which was read in the court this morning by Ms Johnston, Phillips described Connor as awesome.
"He had a great future ahead of him ... He was a junior hunter following in my steps and would have taken over leading the pack."
Phillips said in the affidavit it was hard to live with what happened and no punishment imposed on him could "measure to the grief and guilt I impose on myself every day".
"I wish it was me. I was meant to go before my grandchildren. It is a heavy burden I carry every day. It is a life sentence."
The public gallery was full of family members supporting Phillips.
Justin and Olivia Phillips, the parents of Connor, were not at the sentencing but in a letter read by Judge Snell said: "In our hearts we have forgiven Brian as Connor would have wanted.
"Brian is a kind, caring grandfather, father, father-in-law and brother who always put others first especially his pride and joy - his 10 grandchildren."
In their letter they said any punishment inflicted on Phillips, particularly imprisonment, would cause re-victimisation for the family.
Judge Snell declined the defendant's application for discharge without conviction stating the direct and indirect consequences of conviction were not disproportionate to the offence.
"The offending falls in the lower middle range ... the key rule of using firearms is they must always be pointed in a safe direction. With five children in the area, extra care should have been taken.
"It is very clear the sentence I impose today is nothing compared with how you are treating yourself," Judge Snell said.
