Re: load data help
Hodgdon's data shows 94 grains of Retumbo as max with the 285 Hornady match bullets in the 338LM...
And when you pull apart a Hornady factory 285 grain match load, you find 94 grains of what looks, smells, walks and talks like Retumbo in there... very compressed...
those factory loads shoot great in most rifles, by the way.
But in Lapua cases, the max Retumbo charge would be closer to 93 grains... maybe finding a good node at 92.2 grains or very close to that.
