One thing I will add that I didn't know, but recently learned on another thread is that:
A broadhead adapter isn't properly seated unless it goes in all the way flush. This is due to air being trapped up front. Sometimes it takes a lot of push, the right amount of melted glue,and some rotation to get them seated.
Since learning that, I've got a few to re-do.
Also, I had some two blade, single bevel Grizzlys that looked as though they had some wobble. (I use a horizontal arrow roller tool with the tip of the head up against a solid point like a label on a jar or such, to see if the tip wobbles compared to the stationary object.)
I could not get all of the wobble out of some of my heads no matter how much re-glueing and rotation I did. It wasn't a lot, but not perfect.
Finally, in frustration, I took those heads out and shot them. After several shots they flew just as well as the ones without any wobble, so I figured that was the ultimate test.
