I wanted a two rifle battery that I could use to.take any large animal anywhere in the world. I settled on a .300 WM, and a .458 WM. Two guns are much easier to transport than three or more. But now I think of lion or a NA great bear. Neither of those two seem perfect. I think a .375 H&H or 9.3 x 62 may be the thing I need to add.

So my list is:

.300 Win Mag
.375 H&H (or 9.3x62, or .375 Ruger)
.458 Win Mag (or .458 Lott, if you must)

This is very close, I had a take down Win M70 SS in 338Win mag & had plans on adding 458win barrel but the Gunsmith died that did the first part & it didn’t happen .
160gr to 300gr - 338Win & 300gr to 500gr .458Win covered it all but a nice .500 or .577 would do the rest ?

Being universally DG capable means a minimum of 375H&H (or equivalent).

My choices would be...
375H&H Blaser R8
416RM Blaser R8
500/416NE Krieghoff Big Five or Blaser S2...or possibly a 470NE if I had my druthers.

scoped .450-400 for lion, leopard
.500 NE for everything else.

At least that is what I am going for in the future though I took my leopard with a scoped 9.3x74R double a few years ago.

If you’re interested I know where a pretty PreWar Rigby Sidelock in 9.3x74R is right now. If you’re interested shoot me a PM and I can get you the details.

Would very much like to see pics of that !

Is it a rechambered .400/360NE of some type, I ask as this is regularly done on some .400/360 I have a Westerly Richards .400/360NE unfortunately a true .360 not .366
