EsoxLucius, I've seen in your posts the word superfluous used before, so, I looked it up and the first meaning in my dictionary is "Too Much", how can it be too much when many in the hunting world use calibers such as (your example) .458 Winchester African Magnums? The .457 was designed and chambered in Alaska, where brown bears are common and present all over, especially near running water. What's your reasoning for calling this cartridge superfluous?

Jackfish is quite capable of answering for himself, and would undoubtedly do a better job than I. Nevertheless, I share his indifferent opinion of the .457 WWM.
The WWG web site shows a power comparison which includes a .457 pushing a 350g bullet to 2200fps for 3760fpe. Whoopee. Buffalo Bore sells a 350g load running 2150fps for 3592fpe. I’ve had my .45-70 350g, 2183fps/3703fpe North Fork loads pressure tested and they came in between Buffalo Bore and the old PMC loads in terms of pressure. Frankly, if Buffalo Bore’s 3592fpe isn’t up to the task I wouldn’t want to bet my life on a .457 WWM’s 3760fpe.
The .457 WWM has a “cool” factor, if you’re into that sort of thing, but I prefer using inexpensive and readily available standard .45-70 brass. Giving up a few fps is of no concern to me with this cartridge and in fact I shoot mostly low-power loads except for hunting purposes. My 350g North Fork loads were more than adequate for a buck mule deer at 197 lasered yards and a 6x6 bull elk at 213 yards. Can’t imagine a .457 WWM would have added anything to the party except more recoil and a lot of additional expense.
Don’t know that a 350g would be my choice in Big Bear country. Might go with my “Rhino Blaster” 460g hardcast loads at 1812fps. They only run 3280fpe but they penetrate like there is no tomorrow. Again, if they won’t do the job, the extra edge provided by the .457 WWM is so thin that I wouldn’t want to bet my life on it.
