Oh and the .338-378 WBY it's a great one too
I think the .338 Lapua is so popular because of the Lapua brass. That is why I went with the 338 Lapua. The quality of the brass is excellent and the brass is very strong and ell suited to high pressure. The 338 Lapua is CIP'ed at 67,000 PSI. I realy like mine. I get 2800 FPS with the 300 SMK
This group was shot at 300 yards
The caliper is measuring the outside of the group making center to center .747" that is.238 MOA
Yes the other rounds can do as well, but their are no flies on the 338 Lapua IMHO
