ITEM 21A

The Buffalo Bore Heavy 10 mm ammo is the result of many years of customer's requests that we produce several such loads for the 10 mm.

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 - 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 has always generated enough recoil and pressure to require a pretty stiff recoil spring in your handgun - that, 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 35 fps 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 understand that we get hundreds of emails per day. If we don't answer your email, it is not because we don't value your patronage, but it is because we simply don't have the manpower to answer so many emails. Thank you for your business. Have fun and be safe.

Please note below, my personal velocities taken from real pistols:
➤   1198 fps - Glock model 20 4.6-inch barrel
➤   1223 fps - Colt Delta Elite 5-inch barrel
➤   1244 fps - Para Ordinance 1911 with Nowlin 5-inch barrel

I completely agree with the reviewer before me, J.H. This round will penetrate beyond expectations. As a result, it's a fabulous woods load, where straight line penetration is needed for dangerous game. If 15 of these in a Glock 20 aren't enough protection, you're probably missing with every shot. Accuracy is also fine. To comment on the standard deviation warnings for high-powered ammo in a Glock 20, I chronographed these at 1225 with standard 4.6" barrel. Deviation less than 35 or -. Mine is the Gen 4 with double recoil spring. GOOD STUFF FOR SURE!

This is a penetrator. I shot this load out of a stock Glock 20 through two old pick-up truck doors (sheet steel and regulator) and through 3/4" plywood behind the doors. If it wasn't for the packed dirt mound behind all the "test media" the bullet would still be going. If you want perfect function, good power, and lots of penetration - this is the load.

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
