A Winchester Model 70 Classic is a modern controlled round feed (CRF) action and can be bought in .375 H&H for approximately $2000. A good friend and AH member has shot over 150 head of African animals from the tiny duiker to a bull elephant with this basic rifle.
Dangerous game rifle (DGR) prices are finally rising due to inflation but here's one from a respected dealer for $2000,
The push feed M70's and others are generally less than $2k. There is nothing wrong with them except in our dreams when we are on our backs working another round into the chamber to save us from dangerous beasts... Most people want CRF over push feed rifles.
At $4k bolt action rifles start to be very nice. $6k to $8k will buy a gun of a lifetime. From there a used Heym or Rigby from $15k to over $20k are 98% as nice as can be built. To reach the mythical perfect bolt action that is as nice or fine as ever built, better figure $30k.
A quality double rifle for dangerous game start at around $13k to $15k.
