I see only 4 pellet holes in what I consider a clean kill shot. My rule is 8 to 12 at a minimum. You are beyond my effective range and I would look at 30 to 35 and see what I get. Other lodas might help.
I do not count pellet holes outside the actual vertabrae(neck bones) or actual skull.
Ya I am not going to argue here that it only takes one pellet in the right spot so don't go there!
