Badger, I notice you didn't address the availibilty of these two either. 10mm is much easier to find then 400CB. It is also easier to reload, and according to CorBons own numbers 400CB has nothing over 10mm:
400 Cor-Bon 170gr Bonded SP 1330fps/668ft/lbs 5.00in
10mm 180gr BondedCore SP 1320fps/696ft/lbs 4.60in
The 10mm has 400CB beat hands down in factory offerings by the company that invented 400CB. Pretty telling.
The only real advantage 400CB has is 10mm-like performance in a 45ACP designed pistol (Breechface).

The major advantages of the 400 CB are as follows: As has already been mentioned, it operates at a lower pressure. That means less muzzle blast, noise, and a more flexible round.
What does lower pressure have to do with "flexibility"? And what do I care how loud it is? You already have ears on, so whats the point? Muzzle blast? come on. Neither one of these produces more or less noticable blast than the other.
The round is bottle-necked and will feed more reliably. It headspaces on about 1000% more surface area than the 10mm. Case trimming is not a headspace issue. Finding your brass on the ground is 1000% easier!!!
Feed more reliably then 100%? Whats that, 1000%? These are non-issues, clearly not advantages, since my G20 produces one-hole groups all day.
The 180 grain bullet isn't effective in the 40, 10mm, or 400 CorBon anyways except for maybe hunting.
I don't think so. The most popular and widely used 10mm personal defense round is the Winchester 175ST, awfully close to 180 grains there. On what do you base this comment?
The only real advantage 400CB has is 10mm-like performance in a 45ACP designed pistol (Breechface).
