I have an old Vaquero. To mitigate the recoil, I have the shooting one-handed at about a 3/4 stance allows the gun to bend my elbow and rise past my head. I don%u2019t feel the slap and can shoot a box if I like.
Concentrating on trigger control, I can keep reasonably tight groups

This is some serious stuff! I chronographed 1,303 fps out of my 4.2" Redhawk and 1,738 fps from a carbine. Probably the best factory load available in .45C for hunting big game to the practical range limit of a handgun or stopping dangerous game at close range. Highly recommended.

Holy crap, what a round. I bought these to carry in my Redhawk while bumping around in Alaska's back country. I'd rather have my 45-70 or my 12ga to face down a mad grizzly, but if all I have is my sidearm, these rounds should pack a hell of a punch. They grouped very well and with my Houge grips, the recoil was stout, but not painful. Great round. I love Buffalo Bore products. They outperform everything else, hands down.

Excellent in a .454, but a bit much in a Ruger Redhawk .45LC. Also, will not cycle through lever guns due to cartridge length. But a great load for the .454 if you want plenty of punch but don't want/need a full-house .454 load.

Great ammo. Took it out today with my brand new never shot Ruger super redhawk in 454 casull. This ammo is a hell of a round. Comfortable to shoot with the srh. Didnt chronograph the rounds. Provides more felt recoil than a factory hornady 300gr casull round. I let the gentleman at the range next to me pop off a few and he also felt that it had a sharper more noticeable recoil despite the fact the casull is still quite a bit more powerful. Overall though a great round at a decent price that i can find locally. Will easily handle the toughest of gods two and four legged creatures.!

Holy crap! This stuff is powerful and the recoil confirms it. Before taking a trip to grizzly country, I shot a few rounds of this in my Ruger Vaquero (old) with a 7 1/2" barrel. This stuff kicks hard! In fact, it hurts to shoot it but not just because of the kick itself but because the Vaquero trigger guard would slam into my middle finger. Ouch! No matter how tightly I held the gun (with two hands) it felt like getting my middle finger hit with a hammer. But I have very large thick fingers so that may be part of the problem. I also have very large wrists so, other than the slamming of the trigger guard into my middle finger, it's controllable. This is not ammo that I would want to shoot in that gun for fun. But that's not what it's for, of course. It's for protection in bear country and I wouldn't be worrying about pain in a finger if a bear was charging. However, I may see if I can rig up something to cover the back of the trigger guard to soften the blow. Another problem, and this is with the gun, not the ammunition, is that Vaquero's are light so felt recoil is harder. That wouldn't be as much of an issue with a heavier gun. In addition, the grip on a Vaquero is small. With a larger grip and, especially, one with a grip of some type of rubber or a similar soft material, the problem would be greatly reduced.

This ammo lives up to Buffalo Bore's saying of, "Strictly Business."

Do not buy the 45LC P for any weapon that is not specifically listed in the ad. I bought it for an 1873 Winchester because I wanted higher veloceties for hunting and it was not listed as "NOT intended for" as it does for the new model Vaquero. NOTE: these bullets are engineered to be longer than the normal 45 LC specifically so that they are not used in the 1873 and others like it. When contacting bullet manufacturer they told me that they did it that way to keep the uneducated from using it. Be educated. Use ONLY in those weapons specifically identified in the ad.

Very good grouping and has a kick. My circuit judge loves it.
T Gilmour on 10/06/2010 10:20pm
Easily shoots through 10" of oak. Recoil is stout, but shootable out of my Super Blackhawk Hunter. There isn't a game animal that this couldn't put down. NO DOUBT.

I drew a Montana Moose Tag this year for unit 380. I took this bull at 60 yds with a 4" Ruger Redhawk and your 325 gr. hardcast .45 Colt ammo.

Great round. Manageable recoil plus the 325gr and 260gr have same point of impact from my Blackhawk.

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
