It seems I'm alway's wishing I brought a .243 Win... So I think a .243 Win, a .375 H&H, and a .458 Lott or as mentioned 450 caliber.. But I alway's out of habit instead of a 243 I bring my 06 as a light rifle.. But have found I now only bring a .375 and .458 Lott.. Come to think of it tho, last hunt, my wife with her little Mannlicher Schoenaur carbine (jeez,I can never spell that right) in 7X57 was very very impresive indeed, so I think in retrospect I would drop the 243 and go with the 7X57 as a light rifle..
