.338 Lapua vs. .338 Edge

[el matador]

Just to clarify for those that don't know, the 338 edge has a capacity of 115-116 depending on what brand case is used. I don't know where 122 came from, but it is wrong.

^^^Yep. The two are very close in case capacity. If building on a Rem 700 I would do a 338 RUM or Edge. If you can go custom or want to build on a Weatherby action I'd go with the Lapua.

Referring to grains in H20... And I was wrong... Its 122.5

I know where that number came from, but that doesn't really matter. It is not correct. Franklin is correct.

Maybe I could edit it to say 123.5 and really make you feel good.
