I don't know if its your backstop or what, but those arrows are sticking in at lot of different angles too. A tuning issue maybe, or are you flinching that bad? Maybe a fletching contact problem? That's just what I'm seeing.
The target rotates after pretty much every shot. So after three shots, I generally get three different arra' angles. I've got a little bit of work to do on the tuning, but it should still be grouping better IMO.
