Are these two cartridges dimensionally the same? Thanks?

I believe I read somewhere that they are very slightly differant, but I don't have the dimensions to hand to tell you how. Perhaps someone else posting here has more information. - Dan

There is a slight difference in the neck area. I would go for the Norma since it's C.I.P approved and stanadarized, lapua, Norma, Hornady makes brass and ammo for the norma version
