I loaded and fired some and this still didn't properly form the shoulder or cause the brass to form to my chamber.
I contacted Olin and returned the brass with improperly formed shoulders. As I sorted it, I noticed the brass with the poorly formed shoulders was quite different in color and the inside of the neck didn't show the same forming marks as those that did have the sharp shoulder. Winchester sent me a check for the brass I returned. Just thought I would share this. Lots I received include LG10 and LF03.
The picture I included shows the good brass in a container on the right, the brass I sent back in the container on the left. They were side by side on my desktop, so same lighting.
