The Prime ammo is manufactured by the Ruag Group at the Norma facilities.
It is exactly the same 6.5 Creed brass with a Prime head stamp as was just released by Norma in their 6.5 Creed Sirocco hunting load with a Norma head stamp on it.
I have shot both and took probably the first US game animal with the Sirocco loads when I took my nice white tail in OK this past November. My contact at Norma got me a case of it fresh off the boat before it was even shipped to their dealers so I'd have it in time to take it to the range and the field for my hunt.
