Re: Seating runout
It looks like your cases are good and straight. Are the case mouths square?
I was getting alot of runout when I tried a compressed load .
I then tried seating the bullet a little at a time and checked the runout at each phase .
I was getting very little runout through the first 3/4 of seating and then when I started to compress the powder I was getting the large amount of runout.
I haven't run compressed loads but wanted to try them.
It may help you to try seating and measuring runout on the way down to see where the runout is occuring.
It could be the press, the die, the way the die sits in the threads, even the shellholder can influence runout
If I'm seeing runout I don't like. I seat by carefully aligning the bullet and just barely seating it. Then I turn the case and seat it a little deeper and continue turning and seating until I have it fully seated.
