While I respect your opinion I must disagee. With a 45-70 you are hitting a deer with around 350 grains of bullet and with that much weight you don't need hyper-velocity. With a strong action rifle and handloads or ammo loaded by companies like Garrett and Buffalo Bore you can edge close to some of the factory offerings for the 458 Win Mag. Would you need that for deer, probably not but if bear or other critters that can chomp on you are what you are gunning for then a hot loaded 45-70 will do nicely. Granted your range might be a little more limited than with a modern supermag, but isn't that why it is called hunting instead of shooting?
