I still think Indy is noticing the difference in bullet seating do to not enough neck tension instead of to much.
Do a test on a couple of your loaded rounds. Take a couple that seated hard and a couple that seated with ease. Place the tip of the bullet on your work bench and see if you can push the bullet deeper into the case by hand. My guess is that the ones that seated hard will not move and the one that seated with ease will be pushed into the case. IMO if you can seat the bullet deeper by hand there is not enough neck tension.
If you must have an expander die then get a Lyman "M" die.
I went back over your reply here and I understand more
about that Lee Collet die that I am using. YES .... I do believe that will be all I need.
A detailed reply was somehow lost but I did a complete sorting of all my brass. I now believe that those 25 "loose bullet fit" for some reason.......are my oldest brass. You see ..... I have not been shooting or reloading since about 1989. I had lost track of loadings on the brass I had. BTW... I have purchased new brass and I am starting "number of loadings" records again. The tighter neck tension on theremainder of my older brass
from 1989 is real close to brand new brass.
I think I am on the right track and when I can get out next, I have a Ladder test target with matching details of powder grains ...... and.....some OAL variances recorded.
Wish me luck!!
