Have you considered the difficulty you may have with extraction and ejection? If I am not mistaken that round was designed for use in a horter action similar in size to the Howa designed for 223 and 7.62. you will need a custom bolt head.

Sometimes it is the journey and I can relate as just recently I tried to help a guy do the go down a bad wabbithole. My recent post on this was named the 6mm Hagler. I think that project may have been more doable from a practical standpoint. In the end there are better options like a 6.8 sps (or 7mm-6.8 spc?)
Good Luck
