I've got one that I built out of an 09 Argentine action, but haven't done a lot with. I kind of got sidetracked and never got around to developing a "final" load for it. I've loaded 250's and some stubby little 180's (IIRC). I actually got pretty great accuracy and velocity with the little stubby ones. I think they were designed for the .350 Rem mag, and I bought a bunch of them at a gun show.
It's a little too much gun for normal deer hunting, unless you load it down a little bit, but it's a really good caliber.
I always felt that if I got to the point where I thought it was time to bury my firearms, it was actually time to pick them up..
