Re: 7mm RM for class use
Depends on what you mean by class use. Could you take a precision rifle class with that caliber, sure. I'd run a bullet with a high BC, like a 162 A-max, 168 or 180 Berger VLD. If you reload, I would work up a good load with whatever bullet you plan to use. Years ago I took a class with my 270 Win. So, yeah, it's doable.
