It doesn't mean the die is good or bad. It would mean the relationship between that die and that chamber simply doesn't allow for sufficient sizing is all. Nothing "wrong" with either, just a poor fit of the two together. It's a fine line between just right and not enough sizing and everything has tolerances. Measure as best you can, the largest area ahead of the extractor groove with a good micrometer, not calipers. You need a minimum of about .0005(tenths), sized vs fired. Sized being smaller of course.I guess that is possible, I’m using an LE Wilson 6BRA die, I haven’t heard too many bad things about Wilson dies..
