I'm conflicted here, do I need to trim first than resize or does it matter? Going to be using RCBS X-Dies

Resize, than trim; that's the best way and by far the most consistaint.

RTFM,
ALWAYS trim AFTER sizing.

When you resize, the (bottlenecked) case will get longer-brass that had been stretched widthwise gets pushed lengthwise by the die.  So trimming MUST be done AFTER sizing.

Does that make sense?
