The fired cases look pretty much "normal" to me.
"Long throat", doesn't really come into it. That applies more to bullet seating depth.
I've found that the best seating depth is one caliber of width as a MINIMUM seating depth in the case.
It probably going to jump to the lands whatever you do, but by giving some depth inside the case neck at least gets it "started off right"
This is where bullet profile comes into play. Compare these bullets all seated to the same OAL. Look at the variation of case neck engagement!
I assume the F/L sized is the one to the right as viewed?
Look at the amount the resized brass has been "Set Back"
That's not going to harm your shooting, but it is going to shorten your case life.
You might want to google "Partial Full-Length resizing" & check it out.
