So I am having a weird issue, and I am about to pull my hair out.
Last loading session I loaded up about (300) 6.5x47 Lapua Virgin brass cases.
Berger 130gr AR-Hybrids
42.0 Grains IMR 4451
COAL 2.650
Off the Ogive 2.051
Velocity 2885
Forster Seating Micrometer die.
Went to a PRS class, and shot about 250 of the loaded rounds. Worked great no pressure signs, accurate, etc.
Now I am ready for the PRS season, and need to load the aforementioned now (once fired brass) with the same load after cleaning, prep, and charging with powder.
Now I seat the bullet, and it WILL NOT seat to the original 2.650 COAL / Ogive 2.051 It only seats to COAL of 2.695 / Ogive of 2.096. I thought maybe the die got bumped or changed. So I took it apart, cleaned it, and re-installed it. Measured it and seated a few more rounds with the same results.
Then I wondered if the powder charge was wrong, as it appears to be compressed. So I took some of the previously loaded rounds, measured at the 2.650/2.051, and then pulled the bullets. Weighed the charge and it was also 42.grains. Re-charged the cases, and took the bullets back to the press and seated them (Previous measured 2.650/2.051) Now when seated it goes to 2.695/2.096!!!!!
I can't figure it out. What am I missing, or what do I need to do to get to the old measurements, as those are what worked and I have all my data for before the match next week?
