Wht you will find with the TURBOS is that usually they will pop off when you shoot big game and make an excellent marker for tracking. If you glue them in with a glue such as bohning fletch tite glue , they will be secure in the shaft and still pop off/

Something new turbo shooters will find is that the very high rpms the twisted nock delivers changes how the broadheads cut.
You get a round entrance wound rather than a slice and the entrance wound will be the diameter of your broadhead. With a muzzy broadhead you get a hole that looks like a 12guage slug hit the animal/

A little common sense here. We have been programed to think that a pass through is necessary for a good kill and bleed out.
A conventional fletched arrow only gets an arrow spinning around 400 rpm once it has traveled about 20yds. Usually this makes a slicing entrance wound that will close and not bleed much and we hope for the pass through to allow another hole for bleeding.
The turbo arrow will make a hole larger than the diameter of the shaft that allows for good bleed outs even if you do not get a pass through.
This may possibly increase the odds of a quick kill even if your arrow does not quite hit the mark.
I am attaching a photo of a deer (his first Kill at age 13) Jessie thought he had aimed at the heart of this doe at 25 yds. what ever happened He hit the deer high in the neck and the arrow penetrated and then backed out.
The massive entrance wound left an immediate blood trail and the deer was easily tracked. It ran about 35 yds and dropped from massive bleeding. ( I am not condoning taking or making high risk shots, but this deer would probably been lost with a conventional slicing wound)
I will post another photo of a recent kill by two time world champ with the turbo t-4.
