Definitely acquire a sizing die that has an expander ball built into it. I like the RCBS "X" dies--they do a good job in the calibers I've used it in.
Not with the Lee Collet die. The Lee die is different than any other die. It does not over size the neck then open it back up with an expander ball like all other dies. It squeezes the neck around a mandrel sizing it to the desired size, no over sizing and expanding. It is truly a great design and a great Neck sizing die.
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.
