Why 7 mag. Case Loose on Cartridge Holder

[jimhoodag]

Why would 7 mm magnum cases be very loose on the shell holder? It seems like the area between the case head and the belt has stretched. I have reloaded these mixed cases four or five times with a full length die.

Interesting question. My belted mag cases have always been loose in the shell holder even when new. Are you sure it was not this way before? Do you have any new cases to check aginst?

I don't remember them being that loose, but they could have been. I need to get some new ones to check. Do they stretch in this area?
