Here is a link to targets too
http://lewand.tripod.com/turkeytargets.html
I also think that is average to below average.......take the middle target fromt he link I put up there and visualize that turkey head over you pattern there. I only count the pellet holes that pierce the neck bone, skull or eye of that target and use a rule of thumb of 8 to 12 pellets to develop my lethal range.
Further at the very top of the HNI Trukey forum is a sub forum named Tips and techniques. There is a patterning method posted there. Good read.
