Ballistically the three are very much alike. 6.5 CM brass is more readily availible as a lot of comp shooters are using it and shooting the factory offering. I have access to a LOT of brass. I have less heartburn losing Hornady brass than I would Norma(6CX) or Lapua. A lot of my shooting is out in the field and with snow on the ground, so brass recovery is lousy at best. The other issue with the 6X47 Lapua is small rifle primers misfiring in extreme cold temps. Nothing is more aggrivating than hearing "click" instead of "boom", when you have a coyote standing broadside at 200 meters.....been there, done that.

Luck....is the residue of design...
