A 6.5-06 or 6.5-284 are good options, but have you considered the new Weatherby RPM? It's a mix of the two with more case capacity than either.
The price of Wby brass may be a turn off. Also a new proprietary Wby round. Is it gonna stick around?
We’ll see how it goes. If it stands the test of time.....
IMO, jury’s still out on that one.
