I don't have one, but the Ruger I once shot was pretty brutal with modern factory ammo. Huge cases like the .416 usually don't download well, the low loading density risks pressure excursions. The mildest reputable load I can find is with a 350 cast bullet and AA5744 at 1912 fps. That's still over 2800 fpe for a starting load. I imagine that the good price is due to the current owner's discomfort with the factory recoil....
