Look! It's a thread that's not about 1911s or Glocks!

So. What's the difference between these two cartridges? No info from my favorite spot, ammoguide. Is this a .45 Super vs. .45 SMC kind of thing?

I would suggest getting the information from the horses mouth. Of course the 400 Cor Bon is made by Cor Bon and the 40 Super is produced by Triton Ammo company. Both companies have info on their respective cartridges.

The 400 Corbon case is formed from 45ACP brass. The 40 Super is formed from something similar to a 45 Winchester Magnum case supposodly, a little longer and with thicker case walls. The 400 Corbon tops out at 165 grain bullets due to length. The 40 Super can accept up to 200 grain bullets. The 40 Super was billed as hotter than the Corbon, but I don't remember how much. I believe the Super was capable of 1800fps with a 135 grain bullet! Someone else will have to confirm, but I don't think Triton is still in business. STI used to chamber their Trojan 1911 in 40 Super but no longer catalogues it.

Theorectically,
The 400 Corbon was outdated by the company that developed the round itself. The 45 PowerBall round is actually faster given the same weight bullet from the same barrel length as the 400 Corbon.
Its very close but the PowerBall still has more velocity.......no need to buy out and change the barrel for a slower round...doesnt make sense.
The 45 Super was built around the 45 acp chambering and you basically have to rebuild your 1911/insert gun name here...to use the round. It mimics the ballistics of a 44 mag in your semi auto.....a great idea but IMO, didnt do well...because of the great lengths you have to go to, to use the chambering, in regards to changing your gun around.......
Hope this helps..............
If you want a bonzai s/auto buy a 10mm or desert eage.........
Shoot well

I paraphrase Jeff Copper when he mentioned the 400 Corbon......If you'd expand the neck to .45, then you'd really have something. :D

If that's the case, it only means that CorBon could make a .400 Corbon Pow'rBall that would beat the .45ACP version. It's certainly capable of delivering more muzzle energy. (Personally, I'm not some kind of huge .400 CorBon supporter; I'm just intrigued.)

I also have to disagree about the .45 Super duplicating .44mag ballistics. It's not even close. A better comparison would be to 10mm or .357mag energy, with a slightly larger hole. Furthermore, if you have a sturdy gun (including a modern 1911), a couple of springs will let you shoot .45 Super. It's .460 Rowland that necessitates new barrels and such. (If I reloaded, I would definitely experiment with Super.)

Anyway, the whole CorBon/Triton thing confirmed my suspicions that it's a proprietary issue, like .45SMC. (Guess I should've known that from ".400 CorBon," huh? :) ) Now what's this about Triton being out of business? They make good stuff.

Triton's website has been down for some time now. Also, Cheaper Than Dirt appears to have bought out all Triton's stock and is selling it at a discount.

Usual great information... :rolleyes:

The 45 Super was built around the 45 acp chambering and you basically have to rebuild your 1911/insert gun name here...to use the round. It mimics the ballistics of a 44 mag in your semi auto.....a great idea but IMO, didnt do well...because of the great lengths you have to go to, to use the chambering, in regards to changing your gun around.......

1. Firing .45 Super from a .45 ACP gun doesn't require any modification. That's the WHOLE POINT of the cartridge... use heavier recoil springs and you are in business. Same with .450 SMC, which is essentially the same (different brass & primer type).

2. .45 Super ballistics and .44 Magnum ballistics are nowhere near each other. .45 Super tops out at 230gr @ 1,200 ft/sec from a 6" barrel. .44 Magnum will launch a 330gr bullet over 1,300 ft/sec. .460 Rowland will get you closer (and WILL require a different barrel, etc. to use).

3. .400 Cor-Bon is, ultimately, a pretty lame-o cartridge. Its ballistics are inferior to 10mm Auto (Cor-Bon's own 10mm hunting loads smoke anything in .400 Cor-Bon), you can't really use bullets over 165 grains (vs. 220 for 10mm), it is unreliable from double-stack mags (so much for that Glock 21...), and you give up capacity compared to 10mm to boot.

4. .40 Super puts up more serious numbers, at least with the lighter bullets... 1,800 ft/sec with 135gr bullets and 1,500 ft/sec with 165gr bullets. With heavier bullets, its ballistic advantage over 10mm is pretty small (200gr @ 1,300 ft/sec vs 1,200 ft/sec for Cor-Bon's 10mm "Penetrator" load).

Thanks, shoot well

Lots of information here. Some of it actually almost correct.

There's no problem with o.a.l. in loading heavier-than-165gr. bullets in .400 Cor-Bon. Per Peter Pi, Prez of Cor-Bon, the only reason they stopped loading 180gr. bullets in .400 Cor-Bon was because it almost duplicated their 185gr. +p .45ACP loads. I've personally loaded a bunch of 180gr. bullets in .400 Cor-Bon.

Also, sadly, Triton is out of business, and so you're not going to get any company support for .40 Super. .40 Super and .400 Cor-Bon aren't the the same. .40 Super has a longer case length and offers better ballistics. Most of the .40 Super brass supply has dried up.

Might want to recheck those velocity figures for .40 Super. Using AA#7 or AA#9, velocities of 1500 fps with 180 gr. don't create excessive pressures, per Tony Rumore, who helped develop the .40 Super.

Per another posting, the advantages of the bottleneck .45-class rounds just don't outweigh the disadvantages. Bullet setback is a serious potential problem. Reliable feeding from pre-ban G21 mags is not possible. I can only get around 8 rounds of .40 Super in a 10-rd. G21 mag. I don't have any problem loading 10 rounds of .400 Cor-Bon in a G21 10-rd. mag.

If you use .400 Cor-Bon in a G30. you still have to use the 10-rd. G21 mag, sticking out of the handle.

If you want to hunt with a Glock, get a G20!
