My 375H&H.
Started out as a Model 70 Classic Sporter 7mmSTW I picked up at a gunshow for a song since the stock was gouged up.
I chambered and re-barrelled it with a PacNor or Lilja (can't remember which!) barrel in a "Remington Magnum Sporter" contour.
I Ceracoated all the metal in Graphite black.
Bedded it into a late model Super Grade stock.
It shoots 270 grain whatevers over Reloader 15 and 300 grainers over H4350 into usefully small groups.
After breaking two 6x42 Schitpolds, I put a Swarovski 1.5-6x42 PH scope on it in dual dovetails and all has been well since.
Four leopards, two buffalo, a couple hippos, multiple kudu, gemsbock, zebra, yadda, yadda.
It will do.
