Corbon Ammo anyone done any testing?

[Master Blaster]

I know I have bought boxes of corbon in a couple of different calibers, It seems to me that when I compare them to the standard pressure factory ammo from other manufacturers, like federal and winchester, the Cobons seem much more powerful.

More violent recoil, more destruction to the target. Yet the corbon claims to be standard pressure. I've compared it to my max reloads (max per two different manuals), in the same gun, even at +p levels the corbon seems more powerfull.

Anyone tested Corbon ammo for velocity with a chrono, or pressure in a test setup?

We dont have a consumer reports for ammo and sammi doesnot do independent testing for safety.

You can't get a free lunch in reloading ammo, more powder= more velocity = higher pressure. I find myself just a little afraid and more than a little skeptical that Corbon is really safe ammo, and not dangerously overpressure in most REAL firearms.

What do you folks think????

It has been a while, but Charles Petty did an article in American Handgunner plugging CorBon with pressure and velocity tests. I don't remember where he got the use of a pressure barrel. He found that most of their ammo was loaded at but not over top SAAMI pressures and gave nearly as high velocity as advertised. There was one loading of .40 that was slightly over spec but not more than you might find in the same box of anybody's max loads.

Then there was the .38 Special +P. It was real hot. He figured it at 94% of the pressure of a .357 magnum, way above +P or +P+ rating. They said they would look into it. I shot a little of that vintage ammo in the first titanium snubby in town. It hurt.

CORBON LOADS CLOSER TO SAAMI SPECS THAN ANY COMPANY IN THE INDUSTRY.

THERE ARE INDEED NO FREE LUNCHES BUT THE SIMPLE FACT IS NONE OF THE BIG BOYS WILL DO SO BECAUSE THEY'RE RUN BY A BUNCH OF WHINING LAWYERS AND BEANCOUNTERS.
CORBON IS RUN BY SERIOUS GUNNIES, SHOOTERS, AND EX-LE FOR WHOM GOOD ENUFF AIN'T NEVER GOOD ENOUGH. NEVER!!!!!
Yep, as an employee for the CORBON company I am indeed a prejudiced witness but I have pals in all those other companies who I vacation with every year, have shot tens of thousands of all the calibers all of them make, as they have ours, and we won't be together 10 minutes for a drink afterwards without one of 'em asking " howinell do you guys do that all the time?" My answer to them is always the words above in the CAPS and to a man every year they always agree.
For all the same reasons we do more experimenting in a month's time on new propellents than they've done the past ten years in any one particular caliber and we will switch to a better propellent yet this morning if we discover that this new one is better than the current. They need an edict from 42 law offices and a study from 43 CPA's that'll finally end up saying " DON'T ROCK THE BOAT IT'S BEEN GOOD ENUFF FOR THE PAST TEN YEARS HASN'T IT?!. OUR STUDY ALSO SHOWS IT'LL COST TWO-MILLIONTHS OF A CENT MORE PER ROUND. "
I also want to note here that there are no SAAMI specs for 38+P+ ammunition; the limits are anywhere a manufacturer, or the customer in some cases, wants them to be to achieve a certain result.
So, are we perfect here at CORBON? HELL NO!!!!!! And that is what drives us to seek the holy grail of perfection and what keeps crabby old bastards like me hounding everyone everyday to seek that perfection, to find the PERFECT melding of primer, propellent, brass, and bullet in every single caliber.

OK so what is really going on is that the other guys stuff including what I see in reloading manuals is not really up to the max SAAMI pressure. Other folks are loading weak stuff to prevent lawsuits?

 

[Desert Dog]

Master Blaster,

BINGO!

Corbon and (sorry Terry) Triton ammunition are loaded much closer to the SAAMI maximums with slower burning powder, making their loads superior in every way.

I have done extensive testing with factory ammo (and my handloads) and there is no comparison.

Corbon in particular has a lower standard deviation and more velocity, compared to all the other manufacturers, and even comes pretty close to my handloads. Impressive for a mass marketed product.

Corbon and Triton both load a .40 SW 135 Grain HP and both are good and consistent loads. I did clock the both on the same day and Corbon was 30 or 40 fps faster. I've shot quite a bit of the CorBon stuff and it tends to become my carry load of choice in any given caliber. I've never run across anything that seemed excessively hot and, across the board I find that:
1. It's highly consistent- extreme spreads are very small,
2. The bullets expand massively- generally throwing off frags but maintaining a substantial core remnant intact;
3. Reliability, in any good autopistol is 100 percent;
4. The measured velocities- at least at my elevation and conditions is always higher than advertised.
I've never run across a reason NOT to use CorBon.

Some loads are not loaded to +P levels. For instance, there is a 165 Grain .44 Magnum load that does eight to 12 fps over the advertised 1300 in my 4" Smiths and is loaded to moderate pressures so as to provide a good defense load for these revolvers.

Heavy hunting bullet loads are a reasonable maximum but are still somewhat sedate compaired to some of the hairy loads put up by some of the heavy humpers among the sixgun hunting crowd.

Hello. Most of the Corbon ammunition that I've fired has been in 9mm. I've been very satisfied with the results.

The information below is based on 10-shot averages fired about 10' from the screens.

Velocity for one round of 115 gr Corbon +P JHP's when fired from a Browning Mk III Hi Power....

Average Velocity: 1411 ft/sec
ES: 16
Std. Deviation: 6!!!!!!

When fired from a Springfield Armory XD9....

Average Velocity: 1373 ft/sec
ES: 26
Std. Deviation: 7!!!!!

Fired from a 6" FN Competition Model Hi Power...

Average Velocity: 1466 ft/sec
ES: 43
Std. Deviation: 17

Not all lot numbers will clock the same, but overall, I've had good luck with Corbon ammunition.

Best.

 

[Master Blaster]

Thanks Mr. Camp, as always you provide excellent information.

Last night I took a corbon .32 acp round apart,

It contains 3.5 gr of a small granule flat flake powder which looks alot like bullseye except that it has small brownish red tagents or flakes mixed in. I lit the pile of powder on my "burn tester" and it burned very fast, similar to bullseye.

Anyone have any idea what powder they may be using?

From my nonscientific test it appears to be a fast burning powder.

Thanks.

HMMMM. Alliant Red Dot maybe? S/F...Ken M

 

[Wil Terry]

OH OH OH, I KNOW THE ANSWER TO THIS QUESTION. IT IS

an OEM American smokeless propellent not available in canister grade for handloading.
NOTE THIS WELL: IT IS NOT REPEAT NOT RED DOT.

Corbon ROCKS! When I spend money on ammo and don't roll my own I buy Corbon if they cover caliber. My favorites: the 165grain .44 spec load real fast and accurate in my Bowen conversion Blackhawk. The .454 Casual heavy cast loads are better than I can make. The .32acp is the best HP ammo for caliber. And I can not get close to making anything as good as .357 200grain cast flat point, My God it goes 1200fps out of my 2 1/2" mod 19!I would like to see them make .38 special with this bullet at 850 in snubbies.

 

[Jmurman]

I just used some CorBon 200 gr swc lead reloads in my .45 last week. It worked very well...a little smoky but accurate

 

[Wil Terry]

A note to Jmurman: The CORBON company does NO reloading

And has never loaded nor sold a 45Colt 200gr SWC load of any kind.
In checking their website I do see a 45Colt 200gr JHP self defense load though.

 

[Jmurman]

reloads

Funny...I have two boxes left of CorBon 200 gr 45acp swc lead reloads...they use about 5 differing cases. Win, Fed, S&B, Rem et al....

 

[Wil Terry]

Mr Terry is absolutely correct, the CORBON company

has NEVER made nor sold re-manufactured ammunition, nor ever made nor sold 45ACP cartridges with the 200gr SWC bullet as new ammunition either. I repeat myself, NEVER!!!
Any one selling ammunition as CORBON'S with mixed brass and lead bullets is cheating you bigtime, Sir.

 

[Jmurman]

Don't get all excited about this...but clearly the boxes say Cor Bon 200 gr SWC, the box is blue and they are of differing headstamps. If I had a digital camera I would post the pic. I'm sure that there are Cor Bon reloads that are being made...no one is selling me a bill of goods...

 

[mec]

At first, I thought somebody was just using the old CorBon boxes to hold their reloads like I sometimes do. Then I happened across an obscure reference in an Iraki Mail order catalog. Obviously a degenerate old europe country is trying to capitolize on success. There are a couple of clue to the country of origin in this catalog picture:

 

[Jmurman]

funny pic. I have a confession...my ammo is Black Hills, not Cor Bon. I had emailed Cor Bon and they werer more than willing to help clear up the matter.

My apologies to Terry and the folks at Cor Bon for any confusion.
