Rolf thanks for that information. Certainly moves an old not successful cartridge into the ballistic area it should have been in.

I believe the 358Norma Magnum suffered for one of the same reasons, poor bullet construction.

If Simplex can not make the dies for you, and I would be very surprised if the can't, try Lee and Redding. I have given up on CH4D and would not recommended them to anybody.
