The accuracy of .45 Long Colt ammunition can vary depending on several factors, like the specific load used, the type of firearm used to shoot, the specific load, and the shooter’s skill level. Generally, the .45 Long Colt ammo is considered an accurate and reliable cartridge, especially when fired from a high-quality revolver.

At short ranges like 25 yards or less, most .45 colt loads can produce small groups for target shooting or self-defense purposes. However, the bullet’s trajectory becomes more pronounced at long ranges, making it more difficult to achieve constant accuracy.

It is worth of note that the bullet weight and velocity can affect the accuracy of .45 Long Colt ammo. Heavier bullets are more stable and less affected by wind but drop quickly and have a shorter effective range. Higher velocity loads can extend the effective range of the cartridge, but they may also be more affected by wind and require more skill to shoot accurately.


When comparing .45 Long Colt ammo to .357 Magnum, there are a few key differences to consider of which:

Firstly, the .357 Magnum is a smaller cartridge than the .45 long Colt, which indicates that it has lighter bullet weight and muzzle energy. However, the smaller size of the .357 implies that it can be fired from smaller and more compact firearms, making it a popular choice for self-defense.

Regarding ballistics, the .357 Magnum generally has a flatter trajectory and less recoil than the .45 Long Colt, which makes it easier to shoot accurately and faster. However, forty five long colt  ammo typically is a greater stopping power and is better suited for hunting and other applications where a larger bullet is needed.

In terms of availability, both rounds are widely available online

The choice between the 45 Long Colt and .357 Magnum will largely depend on the intended use and preferences of the shooter.
