That fifth, however, was enough to gain McDowell senior selection to the world championships in the US.
"The New Zealand association falls under the umbrella of the world body, the Single Action Shooting Society (SASS), so our nationals are called regionals but fully sanctioned by the world body," McDowell said.
McDowell junior now has a room loaded with trophies won at various levels and is understood to be the youngest winner of the overall New Zealand title and is rated a serious contender for a world title.
"It began for us as a way of learning gun safety and now me, Bradley and his younger brother Mitchell are into it, although Mitchell is out injured at the moment."
"I won the North Island championship this season, but only because Bradley wasn't there, but I do still get to go the states."
The young McDowell is now passionate about the sport and most of his mates think it's pretty cool they have a sharp shooting cowboy as a friend.
"I won all three categories this year, but I probably favour the pistol," Bradley McDowell said.
"And yeah it does have a romantic connotation to it being a sharp shooting cowboy, but in reality it's far from that. I don't even ride horses for a start. It's more about speed and mental agility. My aim is to become junior world champion in New Mexico next year. I have the trans-Tasman series against Australia in the South Island on Valentine's Day, February 14 as my final lead-up to the worlds, although I will also be competing in two state championships while I am in the US.
"The Oregon state championships are before the worlds and the Wyoming event after the worlds."
The sport is not cheap, though.
"The firearms and other gear are quite expensive but one-off costs. The ammunition is probably the most expensive item. For the world championships alone Bradley will fire off about $2500 worth of ammo," his father said.
Apart from his parents, Bradley's main sponsors include River City Recyclers, Avon McDonalds Equipment, Round Table and Wanganui Veterinary Services.
"I have others and without them I could afford to compete, so I am very grateful for their support. We could always do with more sponsorship, though."
