I happen to have the f.l. die #91524 that comes in that set. With a 'plus' ZZ pin gauge, the neck is a snug .3270.
That's one oddball die set for a 30BR..... -Al
Thank Al I appreciate you measuring it for me.
That will give about .001 - .0015" neck tension on brass turned to .010" But wont size enough for someone turning to .009" . It will work for now for me to get my brass ready to fire and get it fired a few times then Ill send 3 pieces to Harrells or Whidden for a die.
Thanks
