Benefits of 9x23mm Winchester ammunition

What factors to consider when selecting ammo?🔍

When selecting 9x23mm Winchester ammo, there are several important factors to consider to ensure that you choose the right ammunition for your specific needs and preferences. Here are the key factors to keep in mind:

➡️ Intended Use: ⚡ Determine the primary purpose for which you’ll be using the ammunition: self-defense, competition shooting, target practice, or a combination of these. Different use cases may require different types of ammunition.
➡️ Bullet Type:

Full Metal Jacket (FMJ): FMJ bullets have a lead core enclosed in a harder metal (usually copper) jacket. They are known for their penetration capabilities and are commonly used for target practice and training.

Hollow Point (HP): HP bullets are designed to expand upon impact, creating a larger wound channel. They are typically used for self-defense due to their ability to transfer energy more effectively and minimize over-penetration.

➡️ Bullet Weight:

It is measured in grains and affects factors such as recoil, velocity, and terminal ballistics.

Lighter bullets generally result in higher velocities and flatter trajectories, making them suitable for competition shooting and target practice.

Heavier bullets may have more stopping power and better penetration, which can be important for self-defense scenarios.

➡️ Brand Reputation and Quality:  Opt for well-known and reputable ammunition manufacturers. Established brands often have a history of producing reliable and consistent ammunition.
➡️ Firearm Compatibility:  Ensure that the ammunition you choose is compatible with your firearm. Not all handguns chambered in 9x23mm Winchester are designed to handle all bullet types and weights.
➡️ Price and Availability: ⚡ Take into account the cost of the ammunition and its availability in your region. Some specialized ammunition types might be more expensive or harder to find.
➡️ Reloading Potential:  If you’re a hand loader, you might want to consider whether the ammunition is reloadable. This gives you the option to customize loads to your preference and potentially save on costs.

I currently have a 9×23 barrel for my 1911, and despite having it for some time, I’ve yet to do more than examine it closely. However, a notable challenge I’ve encountered is the limited availability of ammo options for this caliber.

    Around two years ago, I acquired a Colt factory 9×23 Winchester. Surprisingly, I’ve come to absolutely love it. Since then, I’ve managed to casually amass over 2,000 rounds of JFP – Winchester USA – 9x23mm Winchester – 124 Grain – 50 Rounds. My advice to fellow enthusiasts is to keep your eyes peeled!

      I’ve noticed that Winchester seems to be one of the few manufacturers that consistently produces 9×23 Winchester ammo. Given this scarcity, you might want to consider the option of reloading. My journey into reloading began about two years before I started getting involved in firearm smithing. Starting small, the initial investment wasn’t much more than what I’d spend on a few thousand rounds of factory ammo. Regardless, I wish you luck. I’ve developed a real fondness for shooting this caliber, and I’m confident that if you give it a try, you’ll be immediately impressed with its performance.

            I came across an advertisement for their available 9mm Largo ammo, which they referred to as 9x23mm. Since then, I’ve noticed ads from other companies also offering 9x23mm Winchester ammo. This got me thinking about whether the two types of ammo are the same or if they’re compatible with a Modelo Super. I’ve been considering the idea of diversifying beyond ball ammo for my pistol, so I’m curious about the specifics of these different ammo options.

              I’ve come to realize that while both the 9mm Largo and the Winchester 9x23mm rounds share the same dimensions (9x23mm), they are not the same cartridge. It’s important to note that the Winchester 9x23mm is loaded to a significantly higher pressure level. Consequently, it’s unsafe to fire the Winchester 9x23mm in a pistol chambered for the 9mm Largo, or any other obsolete rounds that have similar dimensions.

                Observing the 9mm Largo, the .38 Super, the .38 ACP, the 9×23 Winchester, and even the 9mm Steyr, it becomes evident that they all share a common characteristic – their cases are all designated as “9×23”, though the .38s have a semi-rim, and the Steyr has distinct body taper. Interestingly, the term “9mm Largo” refers to the M1910 Bergmann-Bayard cartridge, designed for the pistol of the same name. It was initially adopted by Spain and Denmark, making the Largo (meaning “Long” in Spanish) an early 9mm design. The Winchester 9×23 cartridge, boasting significantly greater power than the other cartridges listed, was essentially a rimless version of the .38 Super.

                  I’ve often wondered why the 9x23mm Winchester cartridge didn’t gain more popularity. It’s a bit reminiscent of the comparison between the 40 S&W and the 10mm. From a purely numerical standpoint, it’s clear that the 9x23mm Winchester offers considerably more energy than even the 9mm +P rounds. So, the question remains: Why isn’t the 9x23mm Winchester more widely embraced for self-defense? Could there be a way to rechamber a standard 9mm (9×19) firearm to accommodate the 9×23 Win?

                    7 months ago

                    In my view, the reason the 9x23mm Winchester didn’t gain widespread adoption is primarily due to its requirement for a larger frame compared to the 9mm, .40 S&W, and .357 Sig. While it does offer higher energy and velocities than these other calibers, the question arises: Why opt for a 9×23 Winchester when you could have a 10mm or a .45 ACP in a firearm of the same size? The 10mm delivers even more power, and in the case of the .45 ACP, factory ammunition tends to be more affordable. A significant factor is the perception that more power can be achieved with the 9mm +P+ load, which can be fired in nearly any 9mm pistol. This viewpoint likely influences the decision-making of those seeking increased power in a 9mm projectile.

                      While I wouldn’t consider myself an expert, I do possess some hands-on experience with shooting and reloading the 9×23 Winchester cartridge. By the time the 9×23 Win. was introduced, the .38 Super had already enjoyed a lengthy 60-year existence. Despite the 9×23 being a commendable cartridge, offering superior performance compared to factory .38 Super loads, I suspect the firmly established status of the .38 Super posed a significant challenge for the relatively new and lesser-known 9×23 Win. to overcome. It’s worth noting that, with ramped barrels, it’s possible for the ballistics of the .38 Super cartridge to safely approximate those of the 9×23 Win. cartridge. On a related note, I’ve personally worked extensively with both factories and reloaded .38 Super, as well as some 9×23 Win. Additionally, I’ve tested various factory 9mm +P and +P+ loads. Notably, factory 9×23 Winchester ammunition exhibits significantly superior ballistics compared to any factory 9mm +P or +P+ loads I’ve evaluated, even when utilizing barrels of the same length.
