A lot of people buy the gun and a box of ammunition and three years later they still haven't finished that box. Granted it isn't too much but the sad fact is that the average person doesn't want to shoot anything more powerful than a .30-06 and even prefers to avoid that level.

That is why if you're patient you can find used like new .375's and .458's for sale for a fraction of their original cost. Most of those rifles seem to come back to a gun shop unused.
