- I did not use the expander die - after sizing, bullets could be seated by placing them on top of the empty case and sliding them carefully into the seating die. I backed off the crimping collet (using the "Seating without Crimping" instructions that came with the die), so that there was no (roll) crimping during the seating.
I was shooting for a COL of 2.225", but it is tough to get a good caliper measurement with that "rubber" tip.
I used the taper crimp die (the fourth die in the Hornady set) to get a diameter of .476 (OK, maybe .477) at the mouth of the case. Most were already there. I measured some of the factory loads; they were all .480.
The factory powder measure was remarkably accurate re repeatability. I was checking after every five rounds, but went to every 10th (measured COL and case mouth at the same frequency) after 20 rounds, since nothing was changing.
Thanks to all the contributors to this and related threads on helping me select equipment and refine (heck, learn) my reloading techniques. Here is a photo of my first reload. I call it the $528.01 round. I will be off to the range in the next couple of days to proof the pudding.
