I have noticed that there is a significant difference in the diameter of the flash-holes in the 357 Sig. Federal and CorBon are "normal" while Speer grabs the decapping pin and pulls it out of the spindle. Any thoughts on which size would yield the best burn?

  I use the Lyman flash hole uniformer/deburrer on all my brass.

  Uniformity is key. The standard flash hole in USA made brass is about .080. European makes tend to be smaller, as small at .060. Getting them all the same will benefit accuracy.
