Heavy 10MM Ammo
180 gr. Jacketed Hollow Point - (1,350 fps/M.E. 728 ft. lbs.)
20 Round Box

ITEM 21B

The Buffalo Bore Heavy 10MM ammo is the result of many years of customers requests that we produce several such loads for the 10MM.

These loads bring out the full potential of the 10MM but operate at standard pressures and as such, are safe to use in any standard 10MM pistol. Please don't phone us and ask if these loads are safe in your 10MM - THEY ARE SAFE--provided your 10MM is a normal operating pistol in good condition.

We are using flash-suppressed powders so your vision will not be materially affected should you be required to drop the hammer in low light.

If you are firing this 10MM ammo from an autoloader and experience high extreme spreads in velocity, it is not the ammo. Here is why and how to remedy the situation.

FULL POWER 10MM AMMO

Full power 10MM ammo has always generated enough recoil and pressure to require a pretty stiff recoil spring in your handgun - this, of course, depends on several variables such as your slide weight, etc. When the cartridge fires, it generates enough pressure/recoil to prematurely open your breech face in some guns. When this happens, the opening breech face has an effect on the burn rate of the powder. This can result in some fairly high extreme spreads in velocity. If you are experiencing extreme velocity spreads of more than 50 fps, simply install a stiffer recoil spring.

FOR EXAMPLE

I have an original Colt Delta Elite. This gun with the factory spring runs extreme spreads of about 35fps with both of these 10MM loads. I am happy with 35 fps, so I leave the Delta Elite as is. I also have a custom built Para Ordnance with a Nowlin barrel. It runs extreme spreads of about 70 fps with its original recoil spring. When I install a spring that is 4 lbs stiffer, the extreme spread drops to about 35 fps. The new Glock model 20 comes with a recoil spring that allows the breech face to open too soon and my new Glock model 20 will get extreme spreads of about 100fps with the factory spring installed. When I go to a stiffer recoil spring, the extreme spreads drop to about 50 fps in my new Glock model 20. Of course, none of this will be an issue in a revolver. None of this will be an issue in real life either, as these high extreme spreads don't hurt accuracy or function. However, I mention this because if you are like me and want things to be as correct as possible, I have outlined the problem and the solution. The industry fixed all these problems initially, by watering down the 10MM ammo over the last several years. The watered-down 10MM ammo does not generate the pressure/recoil to open the breech face early. If you want the full powered 10MM ammo we make, you simply need to tweak your pistol. Or just realize that you are getting some fairly high extreme spreads and ignore it or live with it. It's not hurting anything in reality.

Please note below, my personal velocities taken from real pistols.
➤  1,311 fps - Glock model 20 4.6-inch barrel
➤  1,337 fps - Colt Delta Elite 5-inch barrel
➤  1,351 fps - Para Ordinance 1911 with Nowlin 5-inch barrel

I just purchased a brand new Kimber Rapide Black Ice in 10mm. Waited over a year for it then the only ammunition I could find created nothing but operating issues. After trying 10 brands I dug in and did my research and Buffalo Bore kept coming up. So I ordered a few boxes of Heavy 10 and hit the range. ALL of my problems were solved. No feeding, ejecting or hanging issues. Flawless cycling and the accuracy is second to none. From now on I will only run Heavy 10 through my Rapide! Thanks so much to everyone at Buffalo Bore for such an amazing product!

Best 10MM AMMO on the market to DATE. I'll only buy my AMMO from Buffalo Bore and that's a FACT. My AMMO came in last week and I went up to The Rod and Gun Club here in El Paso, Texas, and had a BLAST LITERALLY. A bit off a learning curve with this New Glock 20 of mine but, I'm digging it for sure. Thanks a TON (BUFFALO BORE)

Shot a box from a Glock 40 with a 22lb recoil spring. Speed varied from 1376 to 1404 fps over a labradar. No hiccups at all. I zero's at 25 and proceeded to ring an 8" steel plate at 100 yards every round. I'm not sure how it will perform on deer but hopefully I'll have an update at the end of the month.

Always been a 10mm fan since I was a child, seeing it in video games and Miami Vice. Bought an EAA Witness Steel In 10mm Auto for my first pistol purchase at 21 and bought some of this stuff. Utah jackrabbits don%u2019t stand a chance, so long as you can hit them with a pistol, something I've not perfected yet, but when you do, it%u2019s like a grenade. Always cycle without fail and recoil is stout, even with a Wolff 22lb spring, but manageable for me with big hands, 6%u20194 245lb. My wife doesn't like them much, but she can handle them. Going to try them for a buck next year, positive they won%u2019t disappoint.

Been shooting this ammo since Glock released the G40 long slide 10mm. Finally got to take a whitetail with it this season. 46 yards through the lungs. Deer ran 15 yards and piled up. Great blood trail. Great penetration (whole way through), broke 3 ribs, and lots of energy transfer on the entry side. Awesome ammo.
Chris on 04/12/2018 06:14pm
Just purchased a glock 29 gen4 and a box of your 180gr . Tested your fine product along side 3 other defensive ammo rounds, definitely can tell the difference. This is my first Buffalo Bore purchase and I'm sold! Ya'll make a very fine product keep up the good work.
Bobby on 11/27/2017 05:41pm
Excellent ammo. With a 22 pound recoil spring and guide rod this ammo performs very well out of the glock model 20. Would definitely recommend
Daryll T on 07/26/2017 05:57am
10mm heavy (180). My first service weapon was a colt delta elite. And I carry one to this date. I can't reload it to any higher ballistics than this factory ammo provides. Everything in detail, was found to be true. This ammo is not watered down to the 40. It is a true 10mm
Harvey on 11/29/2015 10:34pm
This Buffalo Bore 180 gr ammo is highly superb, I have been shooting 10 mm since 1988 with my first Colt Delta Elite so I know 10 mm and this was my first time popping Buffalo ammo, I rate it at the top of the line an I'm going to use it for my daily load with my glocks or 1911's, best 10 mm ammo I have ever shot and I have shot them all, thanks much
Davethehiker on 11/14/2015 05:05pm
I just evaluated it my little Glock-29 with a KKM match barrel. Using a chronometer I measured the velocity of the 180 grain hollow point bullets at 1318 FPS. It was rated at 1350 FPS. I consider my results as remarkably fast for such a small barrel! It fed flawlessly. The recoil was not painful.
Tyler on 05/17/2015 04:40pm
This ammo is awesome. Tight groups and manageable recoil. Easy follow up shots. I carry my g20 sf loaded with the 180 gr jhp everyday. I wouldn't trust my life with anything else.
Captain Jack Zeller on 10/30/2013 02:46pm
This 10MM is advertised at 1350 fps and 728 M.E. I shot it from a Dan Wesson PM7 and got an average velocity of 1382 from a five inch barrel. That is some 768 FPE! This will be my go to round for hunting and carry! Highest velocity recored from 10 feet from muzzle was 1393, and lowest was 1372. You cannot do better than that!
Ian on 03/06/2013 03:59pm
This round works fantastic for wild boar! I took down a 220lbs hog at 15yrds with a G20 in two shots. All my friends and family were impressed with the knock down power of this round. Needless to say, Lake Okeechobee, FL has a few less wild hogs running around.....

Great ammo! I ran across a group of wild hogs during deer season this year and they were well within pistol range. I dropped two dead in there tracks, both with head shots and a third made it 15 yards with a shot to the vitals.I was shooting my colt delta elite 10mm with the 180gr JHP. I highly recommend this ammo for both hunting and defensive roles.
Lee from Texas on 03/30/2010 10:04am
Wonderful ammo. Never once had a malfunction with it, and always holds tight groups. I carry it in my Glock 20SF with a 22lb ISMI recoil spring and captured guide rod.. I chrono an average 1283fps at 658ft lbs of energy with a standard deviation of 24fps and an extreme spread of 55fps.
justin on 06/05/2009 11:27pm
Great ammo holding 1.5 in group @25y with g20 and a 6 in bbl . May I also ad great hog round
doug on 04/19/2009 05:16pm
Awesome! Accurate and powerful. Glock 29 with a new KKM barrel and this ammo gave resulted in such a tight 3 shot group at 10 yards (cloverleaf, all touching) that I stopped shooting to save the rest of the rounds. That's off-hand, no rest, etc. Wow!!
Brian on 03/15/2009 06:08pm
There is nothing out on the market that compares to this 10mm load period! I fired a few rounds of this ammo through my Glock 29 and was amazed at how powerful it was. I have shot many different brands of defensive 10mm ammo and nothing even comes close to this load. If you have a 10mm that you use for a carry gun I would highly recommend this ammo!

Friends and Customers, 08-18-20

IF YOU DO NOT READ THIS, IT IS ON YOU!

All shooters are being inconvenienced with what is happening to our society and the rush it is causing on ammo supplies. We have LOTS of ammo in stock and are making more at a huge volume on a daily basis. If our web site allows you to order any item, that means it is in stock—WE DO NOT TAKE ORDERS FOR ITEMS WE DO NOT HAVE! So, please do not email and ask if items are in stock. If they aren’t, the shopping cart will not take your order.

We have hundreds of customers to get orders to on a daily basis. In order for us to accomplish this for our customers, we ask the following.

  1. Be sure of what you are ordering. You are going to get what you ordered.

  2. Do not contact us and ask to change an order you’ve already placed. When we manually change orders it requires a lot of time that we do not have during this rush and it keeps us from serving all of our customers. If you’d like to change an order, we can no longer do that till things slow down, so simply place another order for more product, but PLEASE, NO MORE CHANGES after the fact!

  3. We NEVER have and never will take ammo exchanges or returns and then turn around and re-sale that ammo to unsuspecting customers as factory new ammo—this is not safe nor is it fair to customers who are buying what they think is new and safe ammo. No ammo is tamper proof! So please stop asking to exchange or get a refund for ammo you ordered, but have changed your mind about.

  4. Please do not contact us and ask for tracking numbers or “when will my ammo ship”? Our system automatically emails out tracking numbers on the orders we ship each day, however, because these emails are coming from a corporation shopping cart, many of these emails may go to your spam folder……..please look there. If it is not in your spam folder, that means we have not yet shipped. At current order rates, we are shipping within 5-7 business days of the time an internet order is placed. Please sit tight. Your ammo will arrive at the same time if you track it or not and will certainly arrive later if we are swamped answering questions instead of getting orders shipped. When 30-50 people per day send emails asking for tracking information and we have to pull that information up, then type it out and email it, it takes a huge portion of our work day that we should be using to ship those orders to customers in need. Please leave us alone so we can serve all of you. (ship to you) It’s a bit selfish, during times of shortages, when so many folks need to protect their families, to slow us down because you ordered carelessly or want to change your order. Right now, we expect you to do your part to help us all get the ammo we need in our troubled country.

These measures are hopefully temporary and will not be needed for long as we enjoy the interaction with our customers, so please, for the time being, be mindful of all those others who are also trying to get ammo during what I think is a societal meltdown/emergency. Hopefully, we can serve you all. We want you and your families to be armed and safe and we wish you the best during these trying times. My biggest concern is that things will worsen yet more, for a while. Until things straighten out in our government and society, we will have to streamline our customer service in order to serve all customers. Thank you for your understanding.

Good shooting and God bless,

Tim Sundles
