I'm totally baffled why one would choose a 6.5x47 over the 260 Rem?
Makes no sense except for maybe superior Lapua brass but that would not be enough for me to choose it.
That is the only reason I have ever been given. You can get Norma .260 brass. I think that should do away with that argument.
brass doesn't have to say Norma to be good brass..
I do just fine necking down Rem 308 nickel brass or Winchester 7/08 and 308 brass for my 260s..
6.5 x 47 is just trying to reinvent the wheel, when compared to a 260..
so for short action, my pick would be the 260 of course..
long action, my favorite is the rare, 6.5 x 57... just because so few folks shoot it, but all you do is neck up 257 Roberts brass and you are good to go..
