The OAL with cast bullets doesn't mean anything useful unless we're both talking about the same bullet, which we aren't, so I can't do much with your measurements.

What bullet are you using, and where is the SWC shoulder relative to the case mouth? It's hard to tell in your pictures but that first pic looks like the shoulder is at or below the case mouth, which will certainly cause problems.

Got a clearer picture of the loaded round?

Look where the SWC shoulder is relative to the case mouth in my first pic above. What do yours do when seated the same way? Ignore the position of the nose and OAL, pay attention to the front edge of the front driving band.
