Was looking at this "wildcat" with interest like others and saw some similarities to the 7mm "Practical" designed by a gentleman in NZ ~2010 with 300WM length, 30 Degree shoulder, and slightly longer neck than 7mmRM. I believe there is still factory taper to case walls however. He demonstrates some pretty impressive performance on his website... ballisticstudies.com . All good stuff!!! I believe he still uses factory 7mmRM dies to "neck size" the cartridge.
