There is nothing inherently wrong with the big magnums and your contention that the magnum craze is just rediculous is, well, just one persons opinion. For myself, while the largest magnum I own is a .300 Win Mag, I am glad that the .300 RUM, 338WM, .338 RUM, .375H&H and .375RUM are available should I choose to buy one. If I was heading to Alaska for a hunt a .338 or .375 in one of the previously listed cartridges would be my companion.
The .30-30 will certainly take any animal in North America, as will a .22 Magnum if properly placed. This does not mean either of them are the best choice for a particular situation. Fortunately the rifle manufacturers do more than consider the needs of most deer hunters when deciding which cartridges to bring to market they consider the needs of the market as a whole. The recent onslaught of short magnums and ultra magnums is not a bad thing at all. Frankly, although I dont own any rifle chambered for Dakota, WSM, SAUM or RUM cartridges, I applaud the innovation they bring. The market will sort out the winners and the losers in due time.
This I know for sure when a hunter spends thousands of dollars on an out-of-state big game hunt in the western states or Alaska, a .30-30 is rarely the most logical choice for the firearm. This is also true a .30-30 can be and often is used at ranges and situations that are inappropriate for the shooter's skill or the .30-30s ability to perform. That is not to say that a magnum will make up for poor placement, but given equal placement I would most often prefer to use a magnum. Indeed, there are many times when proper placement is much easier with a magnum.
Here in Colorado the .300 Win Mag, not the .30-30, is easily and often argued as the best all-around choice for the one-rifle big game hunter.
