Well you have not paid much attention to his loading technique. He has a lee primeing tool, that he has adapted a primer pocket cleaner onto the front, and every shell he loads on there he places the case and gives it a little twist, cleaning the pockets before he seats the primer. So yes he does clean every time, and has done it as long as I have known him, and shot with him. You may not have noticed it because it is very subtle.
Now for beating up on the Spruce goose you may want to check out the SE Ohio match report. I had a bad flyer in the first match, (It is wasn't for that it would have been a nice small group.) but you may want to look and see who shot the smaller groups in the second 2 match's. (Dang it I came close to winning money 3 times, and at the very end, I would just get beat out.)
