Chad - if you had the 6.5x47 cases at the 05 SHOT Show, you should have had the version with LARGE primer pockets...BTW - I think you mean 2006 Shot Show...
We have discussed this a lot over at www.6mmbr.com
and had the first info on the lapua case. We looked at the SM case, and I have some pictures floating around over there as well comparing several:
The one in the pic is the initial LARGE primer pocket version.
Brass issues have been holding the 6x47SM back in the USA - just too much of a PITA to get a hold of any.
Luckily, Lapua came along with the 6.5x47 to help us out [img]/ubbthreads/images/graemlins/wink.gif[/img]
All that being said, I get a solid 2900 out of my 28" 6BR...you should be able to beat that with the 6x47SM...
