Lubing Pellets

I recently tried this. Washed with simple green and rinsed with water. After drying took half and left clean, and dry. Half sprayed with lock-ease graphite lube, and allowed to dry. Shot all 3 versions, based on group size at the same 10m distance with the same rifle both washing alone. And washing with lube shot worse then untouched from the new tin. I am not saying I won't try it again at some point, but it would be with a different pellet/rifle combo. I may try a different lube on the remainder of the only washed pellets as I have nothing to lose there.
