How is it possible that I can run through 100 pieces of once fired Lapua brass that I just annealed, and I push the shoulder back .002 from 1.4675 to 1.4655 and get very consistent results with all pieces of brass within .0005+/-. But when I try to resize my older 4 times fired brass, also just annealed, it just doesn't want to size down. The only way I can get it to push the shoulder back is if I adjust the Forester resizing die even more, but now if I put one of the once fired pieces I already sized (down to 1.4655) through the die (with the new adjustment) it now drops another .002, so now it's .004 pushed back to 1.4635.
It is clear my loads have been too hot, and I need to back off on powder as I am getting signs of pressure, therefore the older 4 times fired brass has been "abused". So maybe it's just no good anymore? It just makes no sense to me that 100 pieces come out to 1.4655, but when I run the old stuff through it's like it was never touched, goes from 1.4675 to 1.4675.
This is for a 6.5x47. I use a Rock Chucker w/ a Forester FL sizing die, expander ball removed because I use a 21st Century mandrel after sizing. I use a very consistent application of lubing my cases as well. The older 4 times fired brass was annealed after the 3rd firing, and then again after the 4th firing right before I tried to resize it today.
The reason I have 100 pieces of this once fired brass to work with is because I was having inconsistencies w/ the older brass and wanted to see what would happen with some fresh brass. In fact I feel that I may have been having some issues w/ the aluminum locking ring on the FL sizing die as it looked kinda of tore up. I was concerned that maybe it was distorted, so I replaced it w/ a new Hornady locking ring that is steel, and I think that helped on the once fired brass. But this older brass is just stubborn as heck and will not cooperate. And before you ask, I am ritualistic about my resizing w/ consistent pulls of the lever and length of time in the die etc. I MEASURED EVERY SINGLE PIECE OF BRASS! I obviously have OCD issues. Thank you for any input on this.
