Ran a new batch today. 16 rounds. Didn't have any more Hornady's left, but some Sierra 125gr FMJ RN came in the mail and I used those.
Made 2 other changes, 1 which could have possibly made a difference. I took off the collars with o rings on the Lee Dies and put in ones that lock with a set screw. I also did use the sizing die this time even though it is new brass.
I measured at every step.
-Initial brass, with in .0015" (.749-.7505
-brass after primer, no change
-bullet length - within .001"
-Final OAL, within .002"
I have a feeling it was either an inconsistency with how the bullets were initially seating or an inconsistency in the diameter where the bullet met the seating die.
I'm not going to loose sleep over it. I'm loading light, didn't have any problems and will continue to over measure the crap out of everything until I get more comfortable with my skills and results.
Thanks for all the help!
