BUFFALO BORE DANGEROUS GAME 458 WINCHESTER MAGNUM
ITEM 458 Win Mag DG 450 SOLID
In my mind, true Dangerous Game cartridges need to be of large bullet diameter. I’ve killed a lot of game animals with many cartridges and I can say for a certainty, that if all else is equal, bullet diameter makes a huge difference in lethality.
458 diameter bullets, if constructed properly, are serious killers. In fact, you really do not need expanding bullets in 458. The bullet diameter alone, with flat nose solids, simply kills assuming sufficient penetration.
This 450 gr. flat nose solid is designed to penetrate many feet through muscle and bone on any mammal. It will not expand or deform and in my rifles, shoots very close to the same point of impact of our 450 gr. TSX load at 150 yards. Normally, I can get shorter lead-based bullets of 450 grs. to achieve around 2,200 fps in the 458 Winchester Magnum. This load generates 2,164 fps in my 18-inch barreled 458. I could have added a couple more grains of powder and compressed the crap out of it with the seated bullet to achieve 2,200 fps, but I do not care for the practice of heavily compressing powder charges with the bullet. This load is slightly compressed, but not heavily compressed.
My 18-inch rifle shoots this bullet slightly faster than my 22-inch rifle. Why? Please read this article “Velocity Versus Barrel Length.” My 18-inch rifle sports an old highly custom Marquart barrel as I had this rifle made over 30 years ago, for kicking around in Coastal Alaska. My 22-inch rifle is a factory Winchester and simply does not have as slick/fast a barrel.
The American gun industry has been duplicitous in claiming bullet velocities. It’s typical for ammo companies to use very long machine mounted test barrels to get very high velocities, but in the real world, with real firearms, you simply will not achieve those results. 23 years ago, Buffalo Bore started to publicly expose this practice and today we are starting to see a few ammo companies get honest with velocities by using real-world guns to generate published velocities. About 35 years ago, (long before I was Buffalo Bore Ammunition) I bought my first chronograph as I had a deep interest in ballistics. (this is being written in 03-2020) I was immediately stunned by how low ACTUAL velocities were, versus published velocities, when it comes to the big ammo companies’ products. When I started Buffalo Bore Ammunition, I chose not to be dishonest regarding published velocities.
➤ 2,141 fps -- Winchester, 22-inch
➤ 2,168 fps -- Custom made, 18-inch
Also, I am not a fan of the under-stabilization of 500 gr. bullets in the 458 Win. Mag. When shooting 500 gr. solids, the bullet will often fail to track straight in medium (read flesh and bone) because the 1-14 twist does not stabilize a bullet that heavy/long, well enough for it to maintain stabilization while busting through medium. Therefore the heaviest bullet we will feature in the 458 Win. Mag., is 450 grs., which is the way the cartridge should have been designed originally as 450 grs. of properly designed bullet, gets the job done with any dangerous African animal and the solids will penetrate/track very straight if they feature a flat nose and these do. A straight tracking 450 gr. solid, will far out-penetrate a 500 gr. solid that gets sideways inside the animal. Original bullets weighing 500 grs. were conceived as more of a marketing practice (WOW! 500 GRS! YIPEE) to the “heavier is better” crowd, than a practical terminal function and in the last couple decades, folks who hunt with the 458 Win. Mag. have learned that 450 gr. bullets penetrate more deeply AS A GENERAL RULE if all else is equal.
Shooters often say stupid things and I’ve heard several of them say that 2,100 fps with a 450 gr. bullet is just a glorified +P 45-70. Um, no! When I load this 450 gr. bullet in a 45-70 case, to max +P velocities, I barely get 1,750 fps……..which by the way, I would use in Africa on Cape Buffalo without hesitation, but I’d prefer 2,100fps if I had the option.
Our propellant selection has allowed us to keep pressures below SAAMI average max. This can become important if your barrel gets filled with rainwater or dust, etc., which raises pressures upon firing and you may find that pulling the trigger with rain in your barrel will raise pressures beyond the rifle design and reliable rifle function can be compromised……..not good when facing an animal that can stomp you into a pile of bloody flesh.
If you insist on using 500 gr. bullets in the 458, the 458 Lott will be the answer for you and we are making that ammo as well, with one 500 gr. TSX option. The Lott generates greater stability to the long/heavy 500 gr. bullet due to its higher velocity. (faster rotation of the bullet) Still, if I hunt Africa with the Lott, (and I’ll be doing that in 2022) I’ll be using 450 gr. bullets for my expanding loads and for my solids.
We are also making a 400 gr. TSX load for the mighty 458 Win. Mag. and Lott, for those that like the 458 for killing giant bears, elk, moose, etc.. The first six times I hunted AK Brown Bear, my guide used a 458 Win. Mag. with 350 gr. hand loaded Hornady bullets and swore by it over the 375 H&H hands down and he had killed many dozens of big bears in his life.
This is serious ammo for serious applications. Use it with confidence. Thank you.

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