Have you ever scrolled back in your messaging app, desperately searching for that one crucial piece of information from a conversation months ago, only to find it's…gone? Many messaging apps have a feature called auto -delete, which automatically deletes older conversations to save storage space or for privacy reasons. While helpful in some cases, it can be incredibly frustrating when important messages vanish. Don't worry; you can usually control this! Let's dive into how to turn off auto-delete for old conversations so you can keep those precious memories and vital data safe. Understanding Auto-Delete and Why It Matters Before we get into the "how-to," let's take a moment to understand why auto-delete exists and why you might want to disable it. Auto-delete features in messaging apps, likeSignal, Telegram, Whats App, and even some email clients , are designed to automatically remove messages after a specified period. This can rang...
Ever felt like your handgun could use just a little more oomph? Like it's good, but not quitegreat? Well, you might be interested in a cartridge that's been turning heads (and punching holes) for nearly a century:the38 Auto Super.
Unpacking the Power of the 38 Auto Super
The. 38 Auto Super, often simply called the. 38 Super, is a semi-rimmed pistol cartridge that traces its roots back to the 1920s. It was originally designed to penetrate the bulletproof vests and automobiles common during the Prohibition era, when law enforcement often found themselves outgunned. But more than just a historical footnote, the .38 Super boasts a compelling performance profile that keeps it relevant even today.
At its core, the .38 Super is a bottlenecked cartridge, meaning the case tapers slightly from the base to the neck. This design, combined with a relatively high operating pressure, allows it to launch a .356-inch diameter bullet (typically 124 or 130 grains) at impressive velocities. We're talking velocities often exceeding 1200 feet per second! That translates to a flatter trajectory and increased energy compared to cartridges like the 9mm Luger or .45 ACP, especially when considering heavier bullets.
Let's put that into perspective. A typical 125-grain 9mm Luger might leave the barrel at around 1150 fps, generating around 368 ft-lbs of energy. A 130-grain .45 ACP often travels at 850 fps, yielding roughly 209 ft-lbs of energy. The. 38 Super, firing a 125-grain bullet at 1250 fps, cranks out over 435 ft-lbs. These are significant differences, especially at extended ranges.
The 38 Super vs. 9mm:A Velocity Comparison
One of the most common comparisons is between the. 38 Superand the 9mm Luger. While both fire similar diameter bullets, the .38 Super consistently delivers higher velocities, especially with heavier bullet weights. This difference in velocity translates to several advantages:
- Flatter Trajectory: A faster bullet drops less over distance, making it easier to achieve accurate hits at longer ranges.
- Increased Energy: More kinetic energy means greater stopping power on the target.
- Improved Penetration: Higher velocity helps the bullet overcome barriers and penetrate deeper.
However, it's important to acknowledge that the 9mm Luger has its own strengths. It's typically more affordable, readily available, and generates less recoil. The choice between the two often comes down to priorities: raw power and extended-range performance (38 Super) versus affordability, availability, and recoil management (9mm).
To further illustrate the difference, consider this table comparing common load data:
| Cartridge | Bullet Weight (grains) | Velocity (fps) | Energy (ft-lbs) |
|---|---|---|---|
| 9mm Luger | 115 | 1150 | 339 |
| 9mm Luger +P | 124 | 1200 | 396 |
| .38 Super | 125 | 1250 | 435 |
| .38 Super +P | 130 | 1300 | 487 |
As you can see, the38 Super generally offers a significant power advantage, even when compared to +P (high-pressure) 9mm loads. This is where the .38 super auto really shines.
Applications of the 38 Auto Super Cartridge
So, where does the. 38 Superreally excel? While it's not as mainstream as some other handgun cartridges, it has carved out a niche for itself in several areas:
- Competition Shooting: The .38 Super is a popular choice in practical shooting disciplines like IPSC (International Practical Shooting Confederation) and USPSA (United States Practical Shooting Association). Its flatter trajectory and increased energy allow competitors to engage targets at longer ranges with greater precision and authority. The .38 super auto helps competitive shooters by providing power and accuracy.
- Hunting: While not ideal for large game, the .38 Super can be effective for hunting smaller animals like varmints or predators at close to medium ranges.
- Self-Defense: The .38 Super's high velocity and energy make it a viable option for self-defense, though its relatively loud report and significant recoil might be deterrents for some shooters.
- Law Enforcement: Though less common today, some law enforcement agencies in the past adopted the .38 Super for its enhanced penetration capabilities.
A particularly interesting application of the .38 Super is in 1911 pistols. Because the 1911 was originally designed for the .45 ACP, which operates at lower pressures, the .38 Super allows for significant performance gains without requiring major modifications to the firearm. This makes it a popular choice for custom 1911 builds.
Understanding 38 Super +P
You'll often encounter the term ".38 Super +P." The "+P" designation indicates that the cartridge is loaded to a higher pressure than standard .38 Super loads. This results in even greater velocities and energy, but it also increases recoil and stress on the firearm.
Important Note: Not all firearms chambered in .38 Super are designed to handle +P ammunition. Always consult the manufacturer's specifications before using +P loads in your handgun. Using +P ammunition in a firearm not rated for it can be dangerous and could damage the firearm.
Choosing a Firearm Chambered in 38 Super Auto
If you're intrigued by the .38 Super and considering adding a firearm chambered in this cartridge to your collection, there are several factors to keep in mind. First, availability can be a consideration. While not as ubiquitous as 9mm or .45 ACP pistols, there are still a number of manufacturers offering firearms chambered in .38 Super.
Some popular choices include:
- 1911-style pistols: Many manufacturers offer 1911s chambered in .38 Super, often with enhanced features and custom options. These are frequently used for competition shooting.
- RIA Rock Island Armory 1911s: Rock Island Armory provides some affordable 1911 platforms in .38 Super for those looking to enter the platform without breaking the bank.
- Custom Builds: Due to the relative rarity, custom .38 Super 1911 builds are popular.
When selecting a firearm, consider the following:
- Reliability: Choose a firearm from a reputable manufacturer with a proven track record for reliability.
- Ergonomics: Ensure the firearm fits comfortably in your hand and that you can easily reach all the controls.
- Recoil Management: The .38 Super generates more recoil than some other handgun cartridges, so consider a firearm with a good recoil management system, such as a heavier frame or a ported barrel.
- Intended Use: Select a firearm that is appropriate for your intended use, whether it's competition, self-defense, or hunting.
A Word on Ammunition
Ammunition availability is another important consideration. While .38 Super ammunition is not as widely available as 9mm or .45 ACP, it can be found at most major gun stores and online retailers. However, expect to pay a premium compared to more common cartridges. Reloading your own .38 Super ammunition can be a cost-effective way to mitigate this expense.
Ultimately, the .38 Super is a fascinating and capable cartridge that offers a unique blend of power and performance. While it may not be for everyone, those who appreciate its capabilities will find it to be a valuable addition to their arsenal. Before making any decisions, research thoroughly and consider your own needs and preferences. Happy shooting!
