A North Pole hunter pierced through both lungs of a moose this fall with a style of broadhead arrow that looks like a circular saw.

The hunt may have been the first time this style of arrow tip, the Blood Therapy OCD, as been used to penetrate moose skin. It likely won’t be the last.

Dallas Petrey initially had doubts when he experimented with the Blood Therapy broadhead.

Petrey works as a bow technician at bow hunting business North Pole Archery Supply. He tested the broadhead after the manufacturer sent the store a box this year.

“It kind of looked weird,” he said. “I remember when Bill, (business owner Bill Huntley) sent me a picture. I said, ‘What is that?’”

In the world of hunting broadhead arrow points, there are two main styles: fixed blade models and mechanical models. The mechanical broadheads usually use springs to release blades when they hit their target. Made by small Pennsylvania-based company, the Blood Therapy broadhead has fixed blades in two directions. Perpendicular to the fixed blades is a sharp metal wheel that rotates.

“If you need a little energy to penetrate, well for example a moose shoulder bone, a lot of broadheads are going to launch into there. We wanted to have the ability to continue on,” said co-owner Jerod Andrews, who founded the business in Green County, Pensylvania, with his brother Justin.

The brothers are deer hunters who’ve been working on the design of the broadhead for a few years. They introduced Blood Therapy in 2015 with a production run of a few thousand, he said. The brothers also make and sell Battle Dust, a vitamin and mineral dust used to attract deer to properties used by hunters.

Petrey tried the Blood Therapy this fall.

He had a drawing permit this year to shoot a cow moose within the Fairbanks Management Area, the hunting area that surrounds Fairbanks and North Pole.

Bowhunters usually practice at ranges with simpler field point arrow tips that don’t tear up targets on impact like broadheads. A week before the moose season started, Petrey took the Blood Therapy broadhead and three other broadheads to the range.

He picked the Blood Therapy because it flew most like his field points at a distance of 70 yards. Petrey hunted with a Matthews Chill X compound bow this year with a 28 inch draw length and 65 pound draw weight.

Petrey found his moose while hunting near the Trans Alaska Oil Pipeline off of Plack Road. He was watching two cows in the area, one of which walked almost into his 60-yard range. He crept forward about 20 yards and took a shot.

“When I released the arrow, you could actually hear the arrow hit her at 58 yards,” he said.

The cow walked about 70 yards before collapsing. She died within about 5 minutes, he said.

In addition to closely matching the flight of his field point, the broadhead did a good job creating a deadly wound as promised. The entire arrow would have likely passed through the moose if not for the 4-inch vane at the base of the arrow, which didn’t fit into the entry wound. The moose meat, which he split with his hunting partner, helped top off two of Petrey’s freezers.

Petrey later called the manufacturer of the broadhead about his hunt. He learned his moose was the first successful moose hunt with the new broadhead that the Andrews brothers had heard about. Bowhunters have used the broadhead mostly to target deer in the Lower 48, although at least one other moose, a bull moose in Canada, fell to the broadhead this year. The broadhead has also been used on bear, antelope, turkey, pigs and elk, according to Andrews.

Although he had a good experience with the new broadhead, Petrey doesn’t expect it will greatly change bowhunting hunting in Alaska. Most customers have a favorite brand and tend to stick with it, he said.
