6mm Creedmoor Alpha munitions brass. My Mighty Armory dies size the neck to .270,my Forester dies to .268. Neck measures with seated bullet .2705 So the Forester has .002 more neck tension than the Mighty Armory. Is this significant?
Two sizing dies

Sounds like the MA die only puts 0.0005" of minus sizing on the neck? Seems very light, can you put a loaded round on your bench tip-down and push the bullet deeper in the case?
Significance is only if one shoots better than the other, and both size the cases enough to hold a bullet to where you can't move it around by hand.
