Cor-Bon: Most Powerful 115 grain 9mm +P denim & ballistic gel shooting test ft. Taurus GX4 3" barrel

[@garrettandrews79]

I saw a ME report involving 2 shots with Corbon 115 grain +P JHP. The projectiles were piercing out the upper back of the suspect (armed home burglar) during the autopsy. Perfect expansion and the suspect was DRT. I know a lot of the old school scalloped JHP do not pass the FBI penetration protocols. One round hit a large valve that supplies the heart with blood. This was in rural Missouri in 2011 and the self-defense pistol was a Sig P250 3.9 inch barrel. The police chief added the Corbon 115 JHP +P for 9mm carriers following the incident. The suspect was a 6 foot 230lb male who had high levels of methamphetamine and alcohol in his system. The rounds caused devastating internal damage to the bad guy and the investigators couldn't believe the terminal effectiveness of the perceived dated old school round.

[@tax905972]

That will work on any subject. The question I have is the number of shots required too put down the threat?

[@noahcount7132]

Thanks for braving the wrath of Old Man Winter to bring us this one, Dave.

[@GeographyCzar]

Thanks for watching, Noah! In January, I have to go after every opportunity to do a new shoot or it's all "compilation" videos from prior years. It happened to be warm that day, and I saw it coming in the forecast, so I picked up some gel mix...

[@OvertonLeveller]

that is not the original Sierra bullet they used to build their fame.

[@therond.patron4959]

The Sierra bullet was whack. So many people loaded that bullet. Before they sold Corbon they came out with their own proprietary bullet. It looks something like the 9BPLE

[@harreeadorable15]

Sierra Power Cavity I think it was.

[@CeltKnight]

Best I ever got with Federal's 9BPLE (115gr +P+) was 1250fps from a 3.5" barrel in a Glock 26. That was on a mild spring day, IIRC, and not in cold weather (which can give lower velocity or so I hear). Either way, these seem to be pretty decent overall for lightly clothed threats. In my neck o'the woods, a bad guy isn't likely to have on more than a t-shirt most of the year.

[@allenbolen9705]

Federal 9 BPLE 115gr +p+ have performed well in heavy clothing test!

[@Valorius]

That is right in line with what you'd expect, since it is advertised as 1300fps from a "duty" handgun. (Typically 4.25-5")

[@highxj]

I recently chronographed several 115 +P and +P+ from several handguns. Check out the Double Tap 115 +P Controlled Expansion. That load clocked 1342 fps from a 3.25" Wilson SFX9, and 1416 from a Sig 365 XL 3.7" barrel!

[@Valorius]

Someone told me Cor bon was out of business. This stuff has always been really powerful, back in the 90s this was the hands down choice for me.

[@Bill_Liggon]

They did sell the business. So it’s not the same family owned company. It’s been that way for years now. It doesn’t have the same projectile it had years ago. It was the big wide open hollow point but not anymore.

[@tylerrodriguez9233]

If you’re looking for high performance ammo, just buy Underwood

[@chucko3879]

I don't see what the hype is here. Their well under 1350 as stated. They clog on clothing barriers. I dont see the hype. There is way better ammo out there. Winchester 127 plus p plus, even a standard pressure generic remington 115 jhp is better. Save your money buy something better. Not impressed but I enjoy your video’s. Keep it going!!!

[@GeographyCzar]

Thanks for the props. 100% underwhelming performance in the denim test for these.

[@YellowHammer26]

[@buckshot4428]

Back in the day Cor Bon was loaded very hot. Not so much anymore it seems.

This is basically.357 SIG. .357 SIG is just a 9 mm in a .40 S&W case.

[@twp616]

Underwood ammo has a 115 grain load at 1400 fps and 501 ft pounds of energy. They are wicked

[@GeographyCzar]

But +P+ if I remember correctly...

[@twp616]

Yes

[@brianbonilla4830]

I haven't seen a box of Corbon's in stores for years

[@mikebott6940]

Corbon is also, if I'm not mistaken, the maker of the modern Glaser slugs. Would love to test some out, but they're expensive.

[@tommccormick9290]

I'd like to see how it performs out of carbine length barrels. I'm sure it would ballistically match a 357 from a handgun. Guessing over 600 ft lbs.

[@BuniBallistics]

Awesome video! Corbon loads their rounds like Underwood and I love it! I wish they were bonded since they shed their jackets from their speed. I have a video of this exact bullet that I'm in the process of editing.

[@thedjruiner]

[@corycarlson8712]

Corbon isn't a good company anymore. I used to love their ammo, their 9mm jhp 115 and 125 classics were great. I bought several boxes awhile back and they are using the absolute cheapest hollow points they can get... If your pushing 9mm hps at that velocity they have to be made for that speed. Whatever cheap pos ones I got in these literally won't fully penetrate a juice bottle. It fragments and comes apart... So disappointed. I did tons of testing with their old jhps that penetrated decently. These look to be sierra hollow points if I had to guess... Definitely not the same as yours, or the old classics. They are just loading anything they can get their hands on. Corbon used to be a respected name. Not anymore.

[@brianbonilla4830]

I want the lead free monolithic copper. DPX, but I never see them anymore.

[@aliman3229]

They used Sierra HPs in the 1990s ammo. I loved that stuff.

[@frankbrowning328]

I expected a significant velocity reduction but a decrease of about 230 fps is a bit much. 1120 fps can be achieved with a 124gr bullet in a 3'' barrel. 1st shot looks like it got plugged with denim. This load doesnt impress me. I'll stick with 124 gr HST

[@GeographyCzar]

Exactly my thoughts - although I might go Speer Gold Dot over HST, but yes, I'll need to go up to 124 grain, clearly. 115 grain 9mm bullets are inadequate IMHO.

[@rob6850]

@@GeographyCzar just curious, what would make you choose Gold Dots over HST?

Have you checked out Buffalo Bore's BUFFALO-BARNES 9mm +P+ LEAD FREE yet? I think it's over 600 ft/lbs at the muzzle. Oh, and I like the channel, good job. Short barrel/discrete defense is a good niche.

[@GeographyCzar]

Thanks! No, I don't do non SAAMI standard ammo. SAAMI recognizes +P in three calibers that I know of, but no +P+ so I'm not going to risk it. For now.

[@Scott.Hughes]

I am still extremely upset with Federal that they discontinued the 147 grain +P HST. I don't know who is running the show at Federal. But they need to be fired.

[@therond.patron4959]

147gr is to heavy IMO people trying to take the 9 mm and turn it into a 45. The 9mm strength is in its speed. Since it is not far from the diameter of a 357 Magnum, the 9 mm is 355

[@hansvollman6987]

Seems kinda weak for these Corbon at lower 1,100 FPS even out of a 3" barrel. Interesting to see what JHP projectile Corbon used here. I picked up a few boxes of this exact same 115 +P ammunition a few months ago in the same blue box packaging, and Corbon appears to use Sierra bullets, the same projectile the Sierra Outdoor Master uses. At least with that lot. It also chronos around 1,240 FPS out of my Glock 26. Not really impressed with ~1120 with 115 +P even in a short barrel. My Sig V Crowns do upper 1100's out of my P365.

[@balancedfordaylight1]

it looks like corbon changed the bullet they are using, at least that projectile looks different than the circa 2013 corbon ammo I have a few boxes of stashed away

[@GeographyCzar]

I didn't know they had changed as this was first box of Cor Bon. A decade ago when I owned my first two 9mm handguns Federal HST had just hit the market and it was "all the rage."

[@geraldkriss1120]

G.K. U.S.A. Unless I see better performance in the testing, I will stay with Hornady Critical Duty and Critical Defense, Federal HST, Speer Gold Dot and Buffalo Bore.

[@GunSam]

Nice! I don't know if it's just me, but I filmed in the snow today and it feels warmer at the 29 degrees I was in than when there's no snow and it's like 35 degrees. I have always wonder why I feel that phenomenon.

[@andywilson8698]

Cause ur a real dude , and snow don't mean shit to you!!! Ur channel is great man , luv the work u do !!!

[@GeographyCzar]

I feel the exact same phenomenon you describe. It's very odd. So interesting to hear it from someone else. I may have mentioned it to my wife or my brother, but they always kinda shrug when I describe the low-key paranormal experiences I have in the outdoors. Thanks for the validation, lol!

[@GeographyCzar]

Glad you enjoy my work! I often question whether I should even mention the conditions I shoot it, but I feel I owe my subs some explanation of why I shoot so infrequently during January and February.

[@therond.patron4959]

Cool test But I wouldn't run such a hot round out of a small pistol. In my SIG 365 I run Winchester Silvertip 115gr. Would you mind doing this test again with a 4 or 4 1/2 inch barrel please?

[@GeographyCzar]

Send me $500 and I'll buy one, LOL! No, I just test what I own, just because I'm monetized doesn't mean I have a budget to go outside the arsenal I would actually use. Maybe someday... The main point of sharing these videos has always been to give the CCW community the same data I gather for personal use. I'd have no use for a 4.5" 9mm as I already have a full size 40 for home defense (not to mention a shotgun or two).

[@therond.patron4959]

Understood

[@buckshot4428]

They must have been running low on powder.

[@GeographyCzar]

Naw, it's just the short barrel. Out of a 5" I'm sure it would reach specs.

[@gsb5w291]

I wonder what length barrel they used for testing because your results were a couple hundred FPS off the advertised velocity.

[@doghousedon1]

250 fps below advertised build velocity with jacket core separation is a high performance round? 150s go faster than that.

[@GeographyCzar]

Yeah, these were disappointing for sure.

[@leadfarmer556]

I got some whinchester ranger t. +p+. These things are pretty hot loads.

[@flexinclouds]

Why would you test these out of a 3" barrel? Unless that is literally the longest barrel gun you have available.. We're not going to get realistic results or fps from a 3"🤦‍♂️ They test those from a 4" barrel btw

[@Texas2Step79]

Cause it's popular for carry due to size..make your own videos

I found out that whoever they use will not ensure them for a +p+ round so that's why it's just advertised +p

[@garyglenn5233]

Buffalo Bore actually makes the most powerful commercial load for the 9mm. It's a 147 gr +p+ putting out over 500 ft lbs of energy. Hot load, but I wouldn't want to put a whole lot of rounds through a small polymer pistol. Besides from the recoil, I'm pretty sure that a round that hot would beat up a small polymer pistol pretty fast. Those rounds would be more useful in a steel frame duty size pistol or a good quality pcc. While they are impressive on paper, I'll stick with my 4" 1911 45. As we learned in elementary school physics, a large slow moving object causes more damage than a fast moving small object. If you've never experienced it, drop a brick on your foot from waist height and then drop a 8" block from the same height and see which one causes the most damage and hurts the most. I can tell you from personal experience that the block is way worse. And of course the rest of the guys in masonry class spent a week laughing their heads off. Well I laughed at their mishaps too, so I deserved it.

[@andywilson8698]

I think he means in Sammi specs, +p+ is outside Sammi specs .

[@GeographyCzar]

100% SAMMI on my channel.

[@flexinclouds]

I dont know where you got your physics from. Drastically higher velocities (even from a much lighter 9mm +p or +p+) will likely cause the same if not more damage than a lot of slow-moving 45 rounds. (Think about the damage a tiny 55gr 556 causes at 3000fps etc). The Speer gold dot 124gr JHP +P rounds I use, claims to move at 1220fps and hit with 410 ft-lbs of energy (which is higher than a lot of .45). And they expand to around .5"... But there is plenty of 9mm that will expand even more (to nearly 1"), and some +p/ +p+ will reach 500+ ft-lbs. All while allowing much higher magazine capacity, and faster follow-up shots imo. I just like the idea of having 15+1 rounds available in my m&p 2.0 4", giving me about twice the capacity of a 45. While also having close to, or equal impact energy per round

[@Mr4twenty.357]

Ok this comment makes me want to trade my 357 sig for 10mm 😮

[@tax905972]

It’s under what the box says. It’s 200 fps shy of what’s advertised .

[@GeographyCzar]

Yes. That's probably a function of the test barrel length v my 3" GX4, which is why I test ammo out of guns that are more representative of the typical carry size than the typical test gun size.

[@tax905972]
