Considering how you're shooting a Lilja barrel and the crimp improves your groups size, you might benefit from an upgrade to some match dies.

The mixed headstamp isn't helping any either. Sometimes that will cause the duel groups like you are seeing in the first photo. Different neck thicknesses can lead to differing neck tension. The crimp could also be evening this out.
