I just bought a batch of "once fired" 44 mag cases from a range. I cleaned them and ran them through the de-primer sizer die. Re primed, charged and began to load 250 Keith style bullets. All was well until I placed a bullet in a case and it fell down onto the powder. My initial assumption was that the bullet was undersized so I tried several more with the same results. Over the course of the next 20 rounds or so this happened 3 more times. I looked at the head stamp, thinking I might have some off the wall sized case. They were all Federal 44 Mags.
Is this brass so tough that it can spring back from the sizing die?
What's going on?
