Please help so confused

In your pic, it looks to me like the case mouth is rounded some, indicating a rather heavy roll-crimp was applied, like your seating die is either milled or adjusted incorrectly. Maybe it's just the pic but can you pull and examine a bullet from one of the completed handloads? Applying a heavy crimp to a bullet without a cannelure will "bulge" a thin-jacketed bullet on either side of the crimp. That's my only thought but take it as you will.
