It would be a fun project, no doubt about that. A lot of people will swear by this or that caliber, some jumping on these new short magnums, some are jumping for the ultra mags. If you are a short action fan, I guess it's interesting, but the new short mags don't do anything that can't be done with a standard or existing magnum chambering. The ultra mags don't really give us anything new, if you compare them to the Weatherby Mags. I personally don't shoot well enough to realize the difference between a 300 H&H Mag, 300 winny, 300 winny short, 300 ultra or 300 Weatherby. None are any better or worse than the original until you get out to 500 or 600 yards, then it's as little as an errant breeze, or a blink. I'm not shooting at a living creature that far away, no way. Too many things happening between the muzzle and the animal. Muzzle to 250 yards, I bet there's not a whisper of a difference in practical trajectory or that an animal would respond differently if hit with one or the other. Same caliber, same bullet weight, etc.... Maybe, I've got it all wrong, though.
