Thanks Lawrence .
What does this show ?

I see grooves formed by the lands in both the skirt and the head .
I do not see any sign of contact to the bore in the section between these grooves .
This is the part of the pellet that is believed to be blown out to make a seal with the bore . Not happening on this pellet , which looks like it has only been pushed / rodded through a barrel .

Ok found a couple pics of a fired and retrieved from down range pellet , i'll have to get help posting the images , but check the portion of pellet that is believed to be blown outwards and drag along the wall of the bore ......
