45 Long Colt Ammo: Buy Bulk .45 Colt In Stock
Looking for 45 Long Colt ammo? You need a dependable supply for your single-action revolver or lever-action carbine, whether you shoot cowboy action matches, hunt, or carry for defense. .45 Colt (also called .45 Long Colt) is a classic, hard-hitting revolver cartridge with roots going back to the Old West. As a result, it remains a favorite among single-action shooters, hunters, and history-minded handloaders alike.
At Prime Tactical Solutions, we stock factory-fresh rounds sourced directly from industry-leading manufacturers. In other words, what you see online is physically ready to pack and ship. Explore our dedicated 45 Long Colt Ammo Category to get started.
Buying in case quantities reduces your cost per round. It also helps you avoid retail shelf shortages, which are common for this classic caliber since fewer manufacturers produce it compared to modern semi-auto rounds. For that reason, we fulfill orders domestically with secure ground shipping across compliant US jurisdictions.
Browse Our 45 Long Colt Cartridge Configurations
.45 Colt’s long history means it’s loaded to different pressure levels depending on the firearm. Because of this, our inventory splits into three core categories:
Lead Round Nose (LRN) & Flat Point Cowboy Action Loads
Traditional cowboy action loads use soft lead bullets at moderate velocities, matching the historical performance of the original cartridge. This makes them the standard choice for single-action revolvers, lever guns, and Cowboy Action Shooting competition.
- 250-Grain LRN: The classic .45 Colt cowboy load, offering authentic recoil and reliable function in original-spec firearms.
- 200-Grain Flat Point: A slightly lighter option favored by competitive cowboy shooters for faster follow-up shots.
Jacketed Hollow Point (JHP) Personal Defense
Manufacturers design standard-pressure JHP rounds to expand reliably while staying safe to fire in older or fixed-sight revolvers. This makes .45 Colt a viable defensive and field-carry option for shooters who prefer a large-bore revolver.
- 225 to 250-Grain JHP: A standard-pressure defensive option, safe for virtually any .45 Colt firearm, including antique and replica revolvers.
+P Heavy Loads for Modern Revolvers
+P .45 Colt ammunition is loaded to significantly higher pressures than standard-pressure rounds. Because of this, it should only be fired in modern, strong-frame revolvers specifically rated for +P .45 Colt — never in original-spec Colt Single Action Army revolvers or replicas.
- 250-Grain +P JHP/HC: A hard-hitting option for hunters and defensive shooters using modern revolvers like the Ruger Blackhawk or Redhawk.
45 Long Colt Ammo: Standard-Pressure vs. +P Loads
New to .45 Colt, or inheriting a classic revolver? Here’s a simple rule of thumb: standard-pressure loads are safe in virtually any .45 Colt firearm, including antiques and replicas, making them the right default choice. +P loads deliver significantly more power, but they demand a modern, strong-frame revolver rated for the extra pressure. Always check your firearm’s rating before buying +P ammunition — this is one caliber where using the wrong pressure level can damage an older gun or injure the shooter.
| Load Type | Muzzle Velocity | Recoil Profile | Primary Use Case | Best For |
|---|---|---|---|---|
| 200-250gr Standard LRN/FP | Moderate | Mild / Classic | Cowboy Action Shooting / General Practice | Single-action revolvers, lever guns, replicas, and antiques |
| 225-250gr Standard JHP | Moderate | Mild / Classic | Personal Defense / Field Carry | Shooters wanting a big-bore defensive option safe in any .45 Colt gun |
| 250gr +P JHP/HC | High | Strong / Heavy | Hunting / Maximum Defense | Modern, strong-frame revolvers only — never antiques or replicas |

Frequently Asked Questions
Is .45 Long Colt the same as .45 ACP?
No. .45 Colt and .45 ACP share the same bullet diameter but are entirely different cartridges with different case lengths and pressures, and they are not interchangeable in any firearm. .45 Colt is a revolver cartridge dating to 1873, while .45 ACP was designed decades later for semi-auto pistols.
Can I fire +P .45 Colt ammunition in any revolver?
No. +P .45 Colt ammunition should only be fired in modern, strong-frame revolvers specifically rated for it, such as certain Ruger Blackhawk or Redhawk models. Firing +P ammunition in an original Colt Single Action Army, a replica, or any firearm not rated for it can cause serious damage and injury.
Is .45 Long Colt good for Cowboy Action Shooting?
Yes, .45 Colt is one of the most historically authentic and widely used calibers in Cowboy Action Shooting, since it was among the original cartridges chambered in period-correct single-action revolvers and lever-action rifles.
Why is .45 Long Colt ammunition more expensive than 9mm?
.45 Colt is a lower-volume, specialty caliber produced by fewer manufacturers than mainstream calibers like 9mm, and each round uses significantly more lead and propellant. This is one of the most common questions from shooters buying 45 Long Colt ammo for the first time. Buying in bulk cases is one of the most effective ways to close that cost gap.
Can I ship .45 Long Colt ammunition to Illinois or New Jersey?
Yes, but both states require ID verification before shipping. Illinois orders need a valid FOID card and matching state ID on file. New Jersey orders need a valid Firearms Purchaser ID card on file. Without this documentation, we can’t ship your order.
