Buffalo Bore 45 101: A Beginner's Guide to Mastering Cowboy Action Shooting Ammunition
Share
The dust of old ghost towns still whispers secrets of the men who built the West with nothing but grit and a reliable six-shooter by their side. In the rugged days of the American frontier, a man’s life often depended on the lead in his belt and the steel in his hand. Today, that spirit lives on through Cowboy Action Shooting (CAS), a sport that isn’t just about pulling a trigger, it’s about a homecoming to a time when honor was won on the range.
If you’re just starting your journey into the world of CAS, you’ve likely realized that choosing the right iron is only half the battle. To truly master the stage, you need the right fuel. That’s where Buffalo Bore 45 comes into the picture. Whether you’re holstering an 1873 Cattleman or a rugged lever-gun, understanding your ammunition is the key to hearing that satisfying clang against the steel target.
The Heartbeat of the Frontier: Why .45 Colt Still Reigns
There’s a reason the .45 Colt (often called .45 Long Colt) has remained the undisputed king of the Wild West. Born in 1872, it was the caliber that tamed the plains. When you slide a heavy .45 round into the cylinder of a classic revolver, you aren’t just loading a cartridge; you’re connecting with a legacy.
In the world of Cowboy Action Shooting, the goal is simple: speed, accuracy, and authenticity. You want a round that feels real but allows you to transition between targets with the grace of a trail-hardened lawman. Buffalo Bore has taken this classic caliber and refined it for the modern shooter who demands vintage performance without the reliability issues of the past.

Why Buffalo Bore 45?
You might ask, "Jason, why can’t I just grab any box off the shelf?" Well, friend, not all lead is created equal. Buffalo Bore has earned a reputation among enthusiasts for creating "strictly big-bore" ammunition that outperforms the watered-down loads often found in big-box retailers.
For the beginner, Buffalo Bore 45 offers a few distinct advantages:
- Standard Pressure Consistency: Many vintage firearms and authentic replicas, like the ones you’ll find on our product pages, aren't designed for high-pressure modern magnums. Buffalo Bore’s standard pressure loads provide the "thump" you want without stressing your heirloom-quality steel.
- Flash-Suppressed Powders: Ever tried shooting a stage in the fading light of a Texas sunset? Muzzle flash can blind you for that critical second shot. Buffalo Bore uses low-flash powders to keep your eyes on the prize.
- Hard-Cast Lead: Their bullets are designed to provide a clean hit. In CAS, you aren't hunting: you're ringing steel. The consistency of their hard-cast lead ensures that your point of aim remains your point of impact.
The Technical Side: Standard vs. Heavy Loads
Saddle up, because this is where we get into the nitty-gritty. When you browse for Buffalo Bore, you’ll notice they offer different "flavors" of the .45.
- Standard Pressure (The CAS Favorite): These are typically 255-grain soft-cast or hard-cast rounds. They mirror the original ballistic profile of the 1870s. They are safe for all modern replicas and even well-maintained vintage pieces.
- Heavy .45 Colt (+P): WARNING. These are not for your Cowboy Action stages. These are "woods loads" meant for stopping a charging bear or dropping a buck. If you try to run these through a standard 1873 Cattleman, you're going to have a very bad day.
For the beginner, stick to the standard pressure. It’s manageable, accurate, and keeps you within the spirit of the competition.

Pairing Your Ammo with the 1873 Cattleman
If the .45 Colt is the heartbeat, the 1873 Cattleman is the body. This iconic "Peacemaker" style revolver is the bread and butter of the Western Gun Store. When you pair a Cattleman with Buffalo Bore 45, you’re holding the pinnacle of frontier technology.
The weight of the Cattleman helps soak up the recoil of the .45, allowing you to cock the hammer and find your next sight picture quickly. It’s a dance between man, machine, and lead. If you’re looking to expand your collection, we have a wide variety of these beauties available here.
Expanding Your Arsenal: The Versatility of the .357
While we’re talking about Buffalo Bore, we can’t ignore the younger, faster brother: the Buffalo Bore 357. While the .45 is the traditional choice, many shooters: especially those looking for even less recoil or higher velocity in a lever-action rifle: opt for the .357 Magnum.
The beauty of the .357 is that your revolver can also shoot .38 Special rounds, which are the "cheater rounds" of the CAS world because they have almost zero kick. However, when you want the rifle to really sing at longer distances, Buffalo Bore 357 heavy loads turn a simple lever-gun into a formidable tool. It’s always good to have options in your range bag.
Beyond the Range: Modern Protection and the Hunt
We know that our customers at Western Gun Store aren’t just shooters; they’re protectors and providers. While Buffalo Bore 45 is your best friend on the CAS stage, you might look for something different when you’re off the clock.
✔ For Home Defense: Many of our regulars swear by Federal Hydra Shok. It’s a modern classic with a proven track record of expansion and stopping power. If you’re keeping a .45 ACP sidearm by the nightstand, this is the gold standard.
✔ For the Hunt: When the season turns and it’s time to head into the brush, Winchester Deer Season XP is a name you can trust. It’s designed specifically for rapid expansion on deer-sized game, ensuring a clean, ethical harvest.

Practical Tips for the Beginner Cowboy
Mastering Cowboy Action Shooting isn't just about buying the right gear; it's about the "how." Here’s a quick checklist to keep you in the winner’s circle:
- Practice the "Thump": The .45 has a unique recoil impulse. It’s a slow push rather than a sharp snap. Spend time at the range getting used to the way the gun rises.
- Clean Your Iron: Lead bullets, especially the authentic ones used in CAS, can leave "fouling" in your barrel. A clean gun is an accurate gun. Don’t let your 1873 Cattleman get gummed up with yesterday’s glory.
- Sight Alignment: Remember, these aren't modern optics. You’re working with blade sights. Consistency in how you hold your grip is everything.
- Saddle Up with a Mentor: The CAS community is one of the friendliest on earth. Don’t be afraid to ask an "Old Timer" for advice on his favorite Buffalo Bore load.
