jut reloaded federal cases obtained by firing federal 45/70 factory ammo. I was not altogether comfortable with the lack of tightness of primer pockets on new Winchester large rifle primers. I also felt the neck expander went into the cases more easily, and that bullet seating took very little force. you could see the bulge in the case where the bottom of the bullet is, suggesting what should be significant neck tension. lucky these rounds are crimped. all the above suggests that the brass cases are actually soft. if factory 45/70 loads have expanded primer pockets, this does not bode well! can anyone comment on federal 45/70 factory ammo brass hardness from experience.? bruce.
