Warped brass

Started reloading with Hornady New Dimension Die set. Forst time for rifle rounds. The seater die started doing this randomly. It's once fired military brass. I was crimping but backed off that but still does it. Any ideas on the cause?

Your seater die is doing that randomly?

Either you didn't trim the brass uniformly and the seater die is impacting the extra brass...

Or, your seater die is also a seater/crimp die and you are randomly bottoming out on an improperly adjusted die.

My money is on the second option.

Thanks. Probably a little of both. I will start with readjusting the die.

probably just the camera angle but those don't even look to be the same cases and bullets and the shoulder looks like it is curved

To keep a seater/crimp die from crimping, use a nickel as a spacer. Put the ram in the up position, screw the die down to the nickel. That works with the Lee dies I've used.

hounddawg, it's just the angle. jimro: I took the die apart, out it back together and set it for no crimp. This seems to have fixed the problem, thanks again
