Another bud who killed a 41" cape in Zim, liked and used the 400 TSX out of his .416 Rigby Ruger Safari Magnum (RSM). He told me this week, he'd go back with that same load and bullet. IIRC, he used a max dose of H-4831. Seems the larger Rigby case does better with slower powder than the .416 Rem. Bill Hober said 4064 was his fav and that's what he loads Swift .416 Rem factory ammo with. If 4064 is good enough for Swift, it's good enough for me and that's what I used.
This bud likes the NPT , while van Rooyen likes the SAF. So, we're trying to find what they prefer.
Agree with the TSX. But, it's not my job to tell those guys what to use....
