Reloading question for .416 Rigby

Member Posts: 101 ✭✭
I have been reloading for 40 years and never had this problem before. The loading data for 350 gr. bullets for the .416 Rigby is scarce. Would it be safe to use 400 gr. powder data and just substitute for 350 gr.? The manuals say to fill the case to at least 90% capacity so I really don't want to use reduced loads.
Theoretically this would be OK: common sense tells me maybe not. Thanks for any advise or published loading data.

416 RIGBY
The following data was developed in a Dakota 76 rifle with a 24-inch barrel. We installed a Leupold 3-9X scope in Leupold rings and Dakota bases. All groups are 3 shots at 100 yards, and we used Norma brass and the Federal 215 primers.

You might want to try this link for North Fork Bullets. He is a very knowledgeable shooter and obviously, reloader. He has photos of recovered bullets with velocity ranges.
