Never have been A fan of redesigning the wheel.
When there are already cartridges in place.
In this case the 338 -06 its been around along time. And I do understand. That sometimes just a new name sells. But being able to see thru all that and knowing common sense isn't common.
I'm not buying into the RPM.
If I want A 338 I have the king of them all in the good old 340 wby.
