Anybody know whether the 416 Ruger is growing in popularity? Seems gun rags cover Rigby and Rem Mag almost exclusively.

Question 2. I have Hornady and Nosler data for 416 Ruger full power 400gr bullets (hang on tight), worked up a 2150fps load comparable to the 450/400 (pretty comfortable), and a Speer 350gr load. Have Barnes manual no. 4, but 416 Ruger data not included. Is it out there anywhere? Thanks.
