What is the purpose of .400 Corbon?

[orangeninja]

Is this a defense or hunting round?

What do you hunt with it? Deer, hog?

How accurate is it?

Does it wear out your gun faster? In this case a 220 sig in .45.

How available is the ammo?

Anyone have experience with it?

 

[tc300mag1]

Ammo is not easy to get here.

Its basically so you can shoot a hot 40 out of your 45 platform kind of like 357 sig on a 40.

I have a barrel for my HK but havent shoot it yet Range here doesnt allow lead.

IMHO is exists because not enough manufacturers are heeding consumer demand for 10mm pistols. it's used for the the same things as 10mm like handgun hunting, a backwoods bear gun and high-powered self defense. the .45acp to .400 corbon conversion is what you buy when you wish x-company made y-model in 10mm but haven't.

from corbon's website:
hunting ammo
10MM -- 180gr BCSP -- 1320fps/696ftlbs
10MM -- 200gr RNPN -- 1200fps/640ftlbs
400CORBON -- 170gr BCSP -- 1330fps/668ftlbs

defensive ammo:
10MM -- 135gr JHP -- 1400fps/588ftlbs
10MM -- 150gr JHP -- 1325fps/585ftlbs
10MM -- 165gr JHP -- 1250fps/573ftlbs
400COR-BON -- 135gr JHP -- 1450fps/630ftlbs
400COR-BON -- 150gr JHP -- 1350fps/607ftlbs
400COR-BON -- 160gr FMJ -- 1200fps/543ftlbs
400COR-BON -- 165gr JHP -- 1300fps/619ftlbs

Just bumping this to the top. Can anyone give a little more info about the 400 Cor-Bon? How does the conversion work? Why is it being manufactured? Does anyone use it? Range Reports?
Thanx in advance.

Corbon's attempt to get into the 10mm market. Corbon 10mm is downloaded so their .400 corbon seems to shine. If you want a hot .40, get a 10mm.

I think .400 Corbon is a cool round but more of a gimmick than actually filling any practical purpose. I like the round enough though that I'll be trying to convert a Springfield Longslide later this year - provided I can find the correctly configured barrel. This is one of the more painless 1911 conversions out there - fit the barrel, bushing, and link, change to a heavier recoil spring, and you're off to the races. The extractor, ejector, slide stop, and magazines all stay the same.

Given the scarcity of 10mm options in new handguns on the market now, I kind of like the option offered by the .400 Corbon. Still looking for a conversion barrel for my Ruger P90. Ruger was going to release that gun in 10mm but backed out. It's more than strong enough to handle it, reliable and cheap.

 

[SniperStraz]

Thanx guys.

I had a glock 21 (i think it was a 21) full sized .45 acp that I had a .400 corbon compensated barrel on.

The ammo is made only by corbon, and it's about $1 per round as I found it. It's a decent load, with a compensated barrel it felt like 9mm recoil. If you don't reload, I wouldn't get this caliber... if you do reload then you can easily just buy brass from starline and any .40 caliber bullet you want.

If you want to hunt with a handgun, buy a revolver. my .02

Most of these loads are pretty tame compared to Doubletaps 10MM ammo , I looked into 400Corbon and decide I'd just find a 10MM . I hope to pick up a EEA Witness in 10 to go with my S&W 1006 .

DoubleTap 10MM specs
165GR......GoldenSabre HP.........744ftlbs/1425fps
180GR......ContExp Hp..............728ftlbs/1350fps
135GR......Nosler HP..................767ftlbs/1600fps
155GR......Gold Dot HP...............750ftlbs/1475fps
165GR......Gold Dot HP...............718ftlbs/1400fps

Fella's;

A .400 Cor-Bon as a backwoods bear gun? Only if I had to. I'd prefer to use it on small, weak, decrepit, old, bears. However, since I regularly go out in the countryside where the bears are most decidedly not small, weak, old, and decrepit, I've opted for a little more oomph.

Here in the northern rockies, where there are both black and grizzly bear, or points north which tend to have larger, nastier, bears, most of us rely on something packing more energy than the .400 Cor-Bon.

I've often thought about getting a conversion barrel from Bar-Sto in .400 Cor-Bon for one of my .45's, & will probably do so in the reasonably near future. But it'll be a social purposes kinda thing, not a bear gun.

400 Corbon is no prize

My first 1911, about a year ago, was in 400 corbon. More uncomfortable to shoot than my 44 mag old model Blackhawk. It beat the slide locking lugs back (Caspian slide)& opened up headspace to dangerous levels. I've since rebarrelled to 45ACP & am a much happier camper. Yes I'm new to the 1911 platform but have been shooting & reloading for 3 & 1/2 decades.

Triphammer,

A most interesting post. Did your pistol have some incorrectly/poorly fit parts? .400 Corbon is fairly mild in the recoil department, relatively speaking, so I was surprised to hear that you found it somewhat uncomfortable.

Sounds like bad barrel fit.

The .400 CB is an interesting round. If you want to work with a .40 and have a .45 already all you need is a new barrel. It served a purpose for a short time when the only improved hollowpoint bullet designs being produced were for .40's and even they needed to be driven faster to expand.

Poorly fited barrel, entirely possible. I've since rebarreled to 45 ACP & the 1911 has become one of my favorite plinkers. Much milder recoil & easier to controll follow up shots. I built another on a Commander slide & this is still easier to shoot than the 5" barreled 400 Corbon

I have a Safari Arms .40 CB barrel I fitted to a Colt 1991A1.

It does work okay - but a couple of caveats:

1. Make sure you have the ammo with small primer pockets, or else you can expect blown primers. Cor-Bon has some useful notes on their website.

2. If you reload, make damn sure your bullets have a tight fit in the case mouth, and a tight crimp. A bullet with a chanellure, crimped in the chanellure, is a good additional precaution. Because of the bottle neck case design, the bullet can very easily get pushed deeper in the case while feeding, which can cause a scary pressure rise.

I also have a 10mm Colt, which I prefer to the fullpower CB, if for no other reason than you get two more rounds in the mag.

One thing I have not heard anyone mention is that, you can drop in a .400 CB barrel into a .45 ACP, load it down with 135 gr subsonic loads, and have a very mild shooting 1911, for less than the cost of a .22 conversion, and way less than the cost of a 9mm 1911, or even a .38 special revo. Mine runs just fine with these light loads.
