How does the .400 Corbon compare ballistically to other, more well known pistol calibers?
How's the recoil of the .400 Corbon out of a full sized, all steel 1911?
I'd also appreciate any other input on the .400 Corbon.

Thanks all,

Kind of what I expected (no replies). Don't see or hear of a lot of guys using that caliber.

I put a .400 corbon barrel in my Sringfield 1911a1. I don't remember what I loaded offhand, but it didnt kick any harder than the 200gr SWC I normally shoot. I took it out after about 30 rounds and haven't had it back in since....

No experience here. Always seemed kinda ridiculous to me. Why put up with .45 ACP magazine cap and midrange 10mm ballistics when you can have more magazine capacity and power by just going with a 10mm Auto?

I understand the appeal of being able to convert cartridges on a .45 ACP platform but some ideas are better than others. The .400 Corbon seems stupid to me. If I want more from my .45, I think I'd rather have a .45 Super.

Beretta Cougar 10mm

Para-Ord P-10/12/13/14 10mm

CZ 97 10mm

Etc, etc.

Until these pistols exist, there will always be a few people interested in the .400 Corbon.

Had an Ed Brown for my SW1911. Worked great, but not enough advantage over the .45 to make it worth the extra ammo expense. Felt like a +P recoil-wise.

RTL,
The single biggest advantage of the .400 Cor-Bon over the 10mm Auto is that it produces considerably less recoil while driving up to 165-gr projectiles at comparable velocities. Of course, you only need to look up and compare the pressures generated by these two cartridges to see why this is the case. .400 Cor-Bon pressures run between 26,000 and 28,000 PSI while legitimate 10mm Auto loads generate at least 36,000 PSI. The hot stuff runs over 38,000 PSI! This is why just about any M1911 set up for the .45 ACP will still hold up to the .400 Cor-Bon, but not the 10mm Auto. Modifications are necessary if you want a 10mm Auto 1911. And even then, more than a number of smiths (e.g. Les Baer) insist that the fatigue threshhold of such guns is staggeringly lower than what it is with the .45 ACP.

Ultimately, however, I must defer to the criticisms of the other boys since the 10mm Auto cartridge really comes to the fore when loaded with 180-gr projectiles. It can get these heavy bullets moving at over 1300 fps, given a 5" barrel, while they just don't even work in the .400 Cor-Bon due to the case being too short for them. I guess that's why I've heard big 10mm Auto fans (e.g. most of the boys at this forum) refer to the .400 Cor-Bon as a lady's 10mm Auto ;) .

400 corbon is good stuff

but from a practical standpoint, where are you going to get your brass to reload it?

you can get 10mm brass as LEAs do shot some 10mm.

Cor-Bon and Starline are the only manufacturers of the brass that I know of. And the Starline is as good as it gets. It's not any more expensive than 10mm Auto stuff, either. Dillon Precision and Midway are two big vendors of Starline brass and they almost always have the .400 Cor-Bon stuff in stock.

If you have a progressive reloading machine or know someone who will reload for you competently and inexpensively, go for it and indulge your fancy. It may not be a 10mm Auto in the end, but it's still a badass little cartridge! And it's pretty versatile, too. Load it down and you're shooting a .40 S&W or .45 ACP. Beef it up and you're hot on the heels of the 10mm Auto.

Maybe I just dont' like 400 Corbon because I cannot recall of any gun that was manufacturered for that caliber.

Only found a custom Caspian 1911 with a 440 Corbon barrel for $2800.

An exotic speciality round - and why buy expensive brass from those two guys?

If you want 40SW to 10mm performance, 10mm is the round.

That Corbon stuff well:

The basic problem with the .400 Corbon is that there are better ways of accomplishing the same goal -- the 10mm or .45 Super come to mind. A bottleneck pistol cartridge is an abomination unto the Lord.:evil:

[duncan]

Amen brother.

But 357 sig is nice and toasty and is being carried by some fine agencies such as the USSS.

If Uncle Sugar was paying for my ammo, I'd shoot whatever he provided. But since I have to reload my own . . . :rolleyes:
