The broadhead is crazy important. You could probably get by without going to a single bevel by running a Magnus or something. Sturdy cut on contact and no crazy cut widths or anything.
When I first went to this arrow, I didn't think it was going to be stopped by a whitetail.
I decided to continue to run Grizztricks. 1 1/4" 4 blade.
I had a buck come in. I was 6-8ft high and he was within 10yds. He was working a scrape basically on the opposite side of an apple tree from me.
I don't know what happened. Maybe he moved as I sent it...maybe I hit an "invisible twig"..I don't know.
Shot was FORWARD of the shoulder but angled back. I got maybe 6-8" of penetration. I couldn't believe he ran off with that much arrow sticking out.
Long story short, I found him bedded in a field 4-6hrs after the shot. His head was swaying and he looked like he was about done. Came back the next morning and he was gone. Instant thought was someone stole him. Nope. He regained his energy and about a month later I got him on a camera.
Cursor is at the entrance. Angled down and back. Guessing it was a single lung stopped by the far shoulder.
Would I have killed him with a single bevel? I don't know. But I'm confident he would have had 2 holes in him.
I've seen slicktricks and grizztricks after encountering bone and it's not pretty. Ribs are fine. Heavy bone and back bone mangles and twists and snaps them and penetration stops. Broadhead and shaft integrity is critical. And they gotta be SHARP. And they gotta fly straight. A 700gr 30% foc arrow that isn't flying true and has some big flimsy blades still isn't going to penetrate well...
After that buck I went to single bevels. I keep a grizztrick in the quiver incase I see a turkey or coyote in season.
Same exact setup except with a single bevel...that's the exit hole. Buck was a couple yards from the base of my tree.
Come straight up the pocket on top of his back and you kinda see the entrance.
He was quartering to me hard with his head down. I put it between the left shoulder and the center line which I figured would have been a center chest exit...and it was.
Id never have taken such a shot if I wasn't confident in the setup. That's a mess of bone to get through before getting into the chest cavity. Impact was so hard the lighter nock backed out slightly and shut off.
He trotted 40yds and did the ole circle flop. The ground stopped the arrow...he took it with him and it eventually pulled out before he fell.
I actually shopped for a bow with a heavier setup in mind. I don't like pulling a ton of weight...I like a longer brace and ATA. I don't have super long arms. I'm shooting a Bowtech Insanity CPXL. The IBO is like 340 or something. Speed doesn't kill. But I do enjoy target shooting and extended ranges.
