I do think the Lapua vs. 243 AI is more efficient, and if wanting the ultimate long range 6mm, might try one if Lapua would mfg. brass, but they have said NO many times for whatever reason. Not a big deal, but if I can K.I.S.S. and not form brass nor use one w/a diff headstamp, I will ...hence the BR. Still have a few new boxes of BR from long ago, stuff lasts a LONG time
True a 6/250 would nigh duplicate the 47.
