The Effective Range🚩

This ammo exhibits an impressive effective range, thanks largely to its high-velocity nature. Traditionally, for the purpose of comparison, the effective range is often defined as the distance at which a weapon can inflict damage on a target with a certain level of assurance.

🟡 For the .22 Tuason Craig Micromagnum, this range is estimated to be around 100 yards (approximately 91 meters) when fired from a handgun and can extend to as far as 200 yards (approximately 183 meters) when shot from a rifle. The cartridge maintains a reasonably flat trajectory up to about 150 yards (137 meters), beyond which the bullet begins to drop sharply.

At 100 yards, this ammo still retains significant velocity, making it suitable for varmint hunting at this distance. However, as with any ammunition, the actual effective range can be influenced by several factors:

  • The barrel length of the firearm. A longer barrel will impart more velocity on the bullet, resulting in a longer effective range.
  • The type of bullet used. Some bullets are designed for more penetration than others, which will affect the effective range.
  • The target. The size and type of target will also affect the effective range. For example, a smaller target will require a shorter effective range than a larger target.
  • The shooter’s skill. A skilled shooter will be able to make more accurate shots, which will extend the effective range.

Battle Of Mini Calibres💡

The .22 Tuason Craig Micromagnum cartridge has a higher muzzle velocity and muzzle energy than the .22 LR cartridge. This means that it will have better penetration and stopping power. However, it is still not as powerful as the 9mm Luger or .223 Remington cartridges.

Let’s summarize the key differences between the four cartridges:

Cartridge Bullet Diameter Muzzle Velocity Muzzle Energy Penetration
.22 TCM .224 in (5.69 mm) 1,350 ft/s (411 m/s) 280 ft·lbf (380 J) Good
.22 LR .224 in (5.69 mm) 1,250 ft/s (381 m/s) 140 ft·lbf (190 J) Fair
9mm Luger .355 in (9.1 mm) 1,150 ft/s (351 m/s) 350 ft·lbf (470 J) Good
.223 Remington .224 in (5.69 mm) 2,300 ft/s (701 m/s) 1,300 ft·lbf (1760 J) Excellent

In light of the above, it is apparent that the choice of ammunition – whether it be .22 TCM, .22LR, 9mm, or .223 – is heavily influenced by the specific requirements and preferences of the shooter. Each of these ammo types has unique characteristics and advantages, from the high velocity and lower recoil of the .22 Tuason Craig Micromagnum to the renowned self-defence capabilities of the 9mm. Therefore, a comprehensive understanding of these different ammunitions, their properties, and their suitable applications is vital for making an informed decision. Ultimately, the most appropriate ammunition is one that best aligns with the shooter’s objectives, whether that be precision shooting, hunting, self-defence, or tactical situations.

Does TCM ammo come in different variants?

The .22 Tuason Craig Micromagnum ammunition indeed comes in a few variants, each designed with specific applications in mind.

✔️  The most common variant is the standard 40-grain jacketed hollow point (JHP) round. This version is designed for high velocity, extending its effective range and enhancing its terminal ballistics. It’s ideal for both self-defence and varmint hunting due to its high speed and the devastating wound channels created by the hollow point design.

✔️ Another variant is the .22 TCM 9R, which was developed for use in guns designed to fire 9mm Luger rounds. The 9R rounds are slightly shorter than the original .22 TCM, allowing them to fit in a 9mm-sized magazine. They have a similar velocity and ballistic performance to the original TCM, making them suitable for a wide range of applications.

✔️ There is also the .22 TCM Rifle, which is a bolt action variant. This variant uses the same.22 TCM ammunition but is designed to be fired from a bolt action rifle. It offers enhanced accuracy and a higher velocity due to the longer barrel length, making it a fantastic choice for small-game hunting and target shooting.

✔️ Lastly, some manufacturers also offer .22 Tuason Craig Micromagnum ammo with different bullet designs, such as soft point or full metal jacket, to cater to the varying needs of shooters. However, these variants are less common.

Is 22 TCM ammo reloadable?

Yes, TCM ammo is reloadable, but there are some important considerations and steps to keep in mind if you want to reload this ammunition. Reloading TCM ammo involves using specific components and equipment designed for the TCM cartridge. Here’s what you should know:

  1. ✅ TCM Brass: You’ll need fired TCM brass cases to reload. Make sure the cases are in good condition, without cracks or signs of excessive wear.
  2. ✅ Reloading Dies: Obtain reloading dies specifically designed for the TCM cartridge. These dies will be necessary for resizing, decapping, seating bullets, and crimping.
  3. ✅ Components: Gather the appropriate reloading components, including small pistol primers and powder suitable for the TCM cartridge. Consult reloading manuals or reputable sources for load data.
  4. ✅ Load Data: Use reliable load data sources to determine the proper powder charge, bullet weight, seating depth, and overall cartridge length for your desired performance level.

Can .22 TCM ammo be lethal?

Yes, this ammunition can be lethal, just like any other type of ammunition. While this cartridge is relatively small in calibre, its high velocity and energy can still cause significant damage to a target. The lethality of any ammunition depends on various factors, including shot placement, bullet design, distance, and the individual’s physiology.

It’s important to note that this cartridge is not typically recommended for self-defence or hunting larger game due to its smaller calibre. While it can be effective in certain scenarios, there are more suitable ammunition choices available for those purposes. Always prioritize safety and choose the appropriate ammunition for your intended use.

How far can a 22 bullet travel in the air?

The distance a 22 bullet can travel in the air depends on a number of factors, including the type of bullet, the gun it is fired from, the angle it is fired, and the wind conditions.

  • 🔘 In general, this bullet can travel up to 1,500 yards. However, this is just an average, and the actual distance can vary greatly. For example, a 22 LR bullet fired from a rifle with a high muzzle velocity can travel much further than a 22 LR bullet fired from a pistol with a lower muzzle velocity.
  • 🔘 The wind can also have a significant impact on the distance a 22 bullet can travel. A headwind will slow the bullet down, while a tailwind will speed it up. This can change the distance the bullet travels by a significant amount.
  • 🔘 It is important to note that the distance a bullet can travel is also affected by the terrain. A bullet that is fired over flat ground will travel much further than a bullet that is fired over hills or mountains.

Here are some additional factors that can affect the distance a 22 bullet can travel:

  • The weight of the bullet
  • The shape of the bullet
  • The velocity of the bullet
  • The temperature of the air
  • The humidity of the air
  • The barometric pressure

It is important to remember that 22 TCM ammo is still a projectile, and it can be dangerous if it is not handled properly. Always follow the safety guidelines when handling firearms and ammunition.

Hi! I experienced case head separation. Help me! What to do((((

    4 months ago
    Reply to  Tener

    Case head separation is a serious problem that can occur when the case head separates from the case body. This can happen for a number of reasons, including:

    💡 Overloading the cartridge: When you overload a cartridge, you are putting more pressure on the case than it is designed to handle. This can cause the case to bulge or even rupture, which can lead to case head separation.
    💡 Improper resizing: If the case is not resized properly, it can be weakened and more likely to separate.
    💡 Defective ammunition: In rare cases, case head separation can be caused by a defective cartridge.

    To solve case head separation, you need to identify the cause of the problem and take steps to correct it. If the problem is overloading, you need to use lighter loads. If the problem is improper resizing, you need to use a resizing die that is properly adjusted. If the problem is defective ammunition, you need to discard the cartridges and purchase new ones from a reputable source.

    Here are some additional tips for preventing case head separation:

    ✔️ Use high-quality ammunition that is designed for your firearm.
    ✔️ Do not overload cartridges.
    ✔️ Use a resizing die that is properly adjusted.
    ✔️ Inspect cartridges regularly for any signs of damage.
    ✔️ If you experience case head separation, stop shooting and have the problem addressed before continuing to shoot.

      I’m curious if there’s a possibility of developing a copper penetrator bullet that could be used for loading. While this type of bullet might result in slightly lower velocities due to reduced powder capacity for accommodating the copper material, the exceptional performance of those cross-shaped penetrators is truly remarkable.

        Hey everyone, quick question: has anyone tried using 22 TCM ammo for varmint hunting? I’m curious to know how it fares against smaller critters like groundhogs and squirrels. Thanks in advance for any insights!

          Reply to  Kev

          ❌ While the 22 TCM cartridge possesses high velocity and a relatively flat trajectory, it might not be the optimal choice for varmint hunting. The primary reason is that the 22 TCM uses a relatively small caliber bullet, which might not provide the desired terminal performance needed for humane and effective varmint hunting.

          ✅ Varmints like groundhogs, prairie dogs, and certain small predators require ammunition with sufficient energy and expansion to ensure a quick and ethical kill. The 22 TCM, with its limited bullet weight and caliber, may not deliver the necessary stopping power for consistent and humane results on these types of game.

          For varmint hunting, cartridges with larger calibers and appropriate bullet designs, such as .223 Remington or .22-250 Remington, are commonly recommended. These cartridges offer better terminal ballistics, accuracy, and versatility for varmint hunting scenarios.

            You’re better off with a more traditional rimfire round like the .22 WMR or .17 HMR for that kind of application.
