RE: how do you count patterns
An interesting concept... but I wonder just how much deflection the pellets undergo after passing through the paper media.
I wouldn't think it's too much of an issue on the closest target, but I bet the results could be misleading after ripping through 3 or 4 sheets of paper on the way to the farthest target.
Add a turkey head to the 30" sheet and you've got two plys per target distance. A good concept, but I don't think it will give true results on actual pellet placement.
Then again, I could be wrong... been wrong before... once. LOL.
