Talking to Snowflake, another 7mm MSM user, and he pointed me toward an article on the 7mm Practical, which is essentially the same thing. So help me interpret what I'm reading here...

If I'm reading this right, he formed the cases using a generic Hornady 7mm neck sizer with a 30 degree shoulder.
Then he used a 7mm Rem Mag seating die.
This is what I've been trying to figure out if I could do in order to make my rifle operational this year, not this coming winter.

Tell me if I'm way off base here thinking I could pull something like this off.
