I'm loading a bunch of .30-06 for hunting season, and I'm having quite a bit of scraping while seating the bullets. This seems to be something new, as I haven't had a significant problem with it before, as long as the bullet was straight when seating. Now, I am getting constant scraping of the bullet as it is seated. There is a pile of copper shavings around the neck when I am done...I imagine this will destroy accuracy.
The cases are neck sized, and I even tried chamfering (is that the right term?) the inside of the case mouth, thinking maybe they were a little rough, but that didn't seem to help. I am loading 200gr Nosler Accubonds, and I am putting them in as straight as possible before seating them, then slowly raising the shell plate.
