WHEW! So as long as the rings around the bullet hole are absent or the same color, all is well? Is that my goal at this point?
It is just one thing that has to be right. Yes, I'd fix that first because your targets are telling us it is so very far out of whack and will stand in the way of further meaningful load development with the 4198.
Lube can fail in the particular system you provide for it in a lot of different ways, CORE is just one, though probably at the top of the list for shooting groups.
