Cast bullet loads??

[Patrick Chadwick]

The LEE factory crimp die seems to put a VERY heavy crimp on it, especially considering the 30 Carbine headspaces on the case mouth.

Then back it off a bit and lock the nut accordingly. With case crimping, I inspect the first rounds under a watchmakers eyeglass, and set the die so the the case mouth is barely tighter than parallel. Without the eyeglass, all you can see is a slight shine on the last fraction of a millimeter, where the crimp die has taken out the flare on the mouth.

To keep this kind of sensitive setting, my dies now have nuts with a locking grub screw. And a witness mark to show if the setting has shifted.
