I was trying to load .40 for the first time. Mixed range brass. My cases out of the resizer were getting a burr from the redding sizing die. I measured the die insert at .415, cases were coming out .417. It was really working the brass, some of which had a slight bulge near the base.
By lubing the cases I was able to load the ammo without putting burrs in the brass, but is this die undersized? I don't think .40 should need lube and the cases get worked smaller than factory ammo that I measured at .420-.423.
