Press Release for Buffalo Bore .460 Rowland® Ammunition

Again, as a result of popular demand, Buffalo Bore has added a new cartridge to its line—the .460 Rowland®.

The .460 Rowland®, as we load it, is squarely at mid 44 magnum power levels.  This means that a person can now carry a 1911 style combat pistol that has the power of a 44 mag. revolver, but is slimmer, faster to reload, faster to shoot and holds nine rounds instead of a revolver’s six.  The .460 Rowland® casing is simply a 45 ACP case that has been slightly lengthened so it won’t chamber in a 45 ACP chamber.  It also has a stronger web area in the casing, so as to avoid "blowouts".

To acquire .460 Rowland® test guns, I sent two of my 1911 45 acp pistols to Clark Custom Guns and had them install their .460 Rowland® conversion kits which at the time were being made by Johnny Rowland. To date the converted 1911’s work great. I can fire a 255gr. hard cast bullet @ 1300 fps or a 230gr. FMJ-FN bullet @ 1350 fps. What a great "woods" pistol that still maintains combat pistol qualities.

We are using flash suppressed powders in each .460 Rowland® load, so that if you have to shoot a bear or “bad guy” in the dark, the muzzle flash will not blind the shooter and we feel this feature is a big tactical advantage as most civilian shootings in America, occur in low light and we are willing to bet that most emergency wildlife shootings in the wilderness will be in low light too.

Note my real world velocities (below) from real world pistols, not laboratory test barrels.

It should be noted that my .460 Rowland® conversions are Clark Custom Gun conversions. I did not try this ammunition in conversions sold by anyone other than Clark which at the time, those conversions were being supplied to Clark by Johnny Rowland. This ammunition was reliable and safe in my test conversions, but I cannot verify the reliability or safety of this ammunition in conversions done by anyone that is not using Johnny Rowland's specifications.

All current conversion kits being made to Johnny Rowland's specifications can now be found at

Friends and Customers, 08-18-20


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
