Boy that 250 at 2700 would be a hammer!! Gonna have to play around when the weather gets better.
That's full throttle 338 Win. mag ballistics out of an '06 size case. Interesting.
It sounds like a fair bit more than my shoulder would be up for. As it is, 250's @ 2,500 fps usually make for abbreviated range sessions.
I did notice, though, that lots of their loads across several cartridges incorporate 4000 MR powder. I have a pound that's been sitting unopened on the shelf for a good year plus. I might have to play with it some.
