I'm shooting a standard Mark V in 6.5 RPM. It's a solid caliber, ammo can be expensive, but since it's still pretty uncommon there isn't a crazy demand in my area. Keep an eye out at sportsman's wh. I've found the wby-branded silver box shoots as well if not better than the gold box
Anything .264 is pretty unexciting to me but where the RPM gets my juices flowing a bit is the upsizing options. For a guy sitting on a standard bolt face action but wants some magnum gas tank offerings this case is a great option. Size it up to a .284 and roll.
I always hear those rumors too about norma but I'm on firing number 12 on my 300 wsm and still going strong. Until peterson 28 nosler I was necking up norma 26 nosler brass as well with no issues. Size properly, anneal, and I'd bet a lot of money I'd get 10 on the rpm
