Think you might struggle with case volume with 140gr in a 6.5x47 unless the throat has been cut very long.I dont think you'd want to shoot anything more than 150gn in a 7x47 would you due to the low MV? In which case, go for the 6.5x47. You can still go up to 140gn (or even 150gn?) with better BC than the same weight 7mm bullets?
I reckon it may be a soft shooting round of 130/140gr bullets for stalking.......and will be soft enough for the missus to use.
The thought was originally to go down the 6.5x47L, and is still an option. Seeing that there is a 6x47L, a 6.5x47 and 30x47L, I would have thought there would have been a consideration of a 7x47L by now to a greater extent......
