123g Lapua vs. 123g SMK

[skinewmexico]

Is there a huge difference in these two bullets, in a 6.5X47 Lapua? I was trying to get an idea of how much loads would have to change. Thanks.

I have not used the 123 Sierra in my 260 but I do use the same loads for 142 SMK and the 139 Lapua. I would guess that onless you were running on the very edge you should be fine.

i am shooting 6.5x47L. i used the same load for both at 550yds to compare.
i am currently away,but if my memory is still working.the 123 scenars grouped 2 3/4" and the 123SMK 3" for 3 shots,needing 2MOA wind correction too)it was rather windy.
the 123 scenars needed one 1/4" click,.250MOA)to be at the same height
