One of the most complex and widely discussed issues within the modern firearms community is the choice of caliber for long range shooting. This long-range caliber topic has been discussed in many different areas, including PRS, tactics, military / law enforcement, hunting, and more.

The truth is, there's more than one long-distance meter that's perfect for every job, and there are many factors to consider. Different shooters have different calibers that are more suitable for a particular goal or mission.

1- 5.56mm /.223 Remington

History. This round was developed in collaboration with the AR-15 rifle in the early 1960s. The US Army has determined that the average rifle group is more effective at targeting with a 5.56mm rifle than the average rifle group. Heavier 7.62 retreat. tuigs. Ammunition has been significantly reduced in weight. In other words, the gun can be lighter. However, this pattern changed the tactics of the US military and subsequent NATO allies. First Thought: The .223 Remington offers excellent options for beginner weekend fighters with limited range of equipment. It is also ideal for those interested in hunting medium and nearby pests.

Snoop speed: The average MV for .223 is 3100fps. Shells are available in the 40-90 grain range and MVs are also in the 3400-2600fps range. The walking distance also changes the average MV. Rule of thumb: 30-50fps per 1-inch barrel gained or lost.

Ballistic coefficient: Similar to MV, .223 caps are very different. The most common .223 round of LR performance is the Sierra Match King 77gr ATM, so use this. G7 vC ~ 0.202.

Residual power: Snout: 1 316 vt-lbs 500 m: 470 vt-lbs 1000 m: 165 vt-lbs 1500 m: 108 vt-lbs

Transonic speed range: 800 m @ 1128 fps

Backlash Status: One of the best things about building a .223 rifle is that shooters of all ages can manage backlash. There are few setbacks.

Cross-Platform Use-Almost any rifle action can create a .223 rifle. It's also the most popular modular rifle ... the most popular caliber of the AR-15. With .223 the possibilities are endless.

Ammo Availability: Factory ammunition is available almost everywhere for about 30 cents per round, but as mentioned earlier, prices vary widely. Barrel Life-The barrel life is highly dependent on the type of ammunition and the rate of fire of the weapon (barrel temperature). Half-lives range from 4,000 to 7,000 laps.

Overall Practical: .223 is great for inexperienced and / or young shooters. Shooting guinea pigs at 500 yards is a great choice. For rifle platforms, this caliber is ideal for building highly modular and dynamic setups. As a candidate for the best long-distance caliber overall?

The .223 has a very limited range compared to other cartridges due to features such as lack of projectile mass. This results in .223 performance in strong wind conditions and no energy retention to cover long distances. .. Don't be a pattern.

2- 224 Valkyrie

History: .224 Valkyrie was a child of a federal experiment in 2017 attacking a 1,000-yard competition track (dominantly a .30 caliber class pattern) with a small .22 caliber projectile. To make it an already proven case, the 6.8 SPC (Special Purpose Cartridge) has been scaled down to fit a .22 caliber projectile. This basically means that the opening of the box where the bullets are placed is tightened from 6.8mm to 5.7mm. That 1mm difference means a significant increase in MV.

First thought: This pattern is an interesting example of innovation to solve a fairly difficult problem. Before the start, the idea of pushing a 75-grain projectile over 1000 meters was rare. The market is still catching up as the .224 is so new. There aren't many production guns in the budget option. Especially in the field of architectural behavior.

I think this pattern will be useful for long-distance communities in the future. Valkyrie's main drawbacks are the same as .223. Stopping power is limited because the projectile does not have much mass. For hunters, the average game is at the limit of this caliber. Nose Velocity: MV values of .224 range from 2,700 fps (90 grain projectiles) to 3,400 fps (60 grain projectiles).

Ballistic Coefficient-A projectile specifically designed for long range shooting is the 90-grain Sierra Matching. G1 BC: .563 G7 BC: .274.

Residual power: Nozzle: 1 456 ft-lbs 500 m: 660 ft-lbs 1000 m: 248 ft-lbs 1500 m: 162 ft-lbs

Transonic speed range: 1,000 m @ 1,114 fps.

Recurrence status: Minimal. Many shooters claim that .224 has about half the felt backlash of .308.

Multi-Platform Use: This case is designed for use outside the AR platform for Precision Rifle Series (PRS) matches. As mentioned earlier, .224 Valkyrie was not enough for a standard rifle maker. When inventory similar to the Remington 700 begins to pile up at .224, I think it will be a viable option for more skilled chargers looking for a 1,000 yard build with a low recoil caliber. This pattern remains the same and is ideal for PRS shooters. Ammunition Availability: There are several factory loads on the market today. Burns, Hornady, Federal and Burger all charge $ 0.60 to $ 1.30 per round. Chargers can stretch Valkyrie by playing with different powders, bullet sheet depths, and projectile types.

Keg Life: Finding data on barrel life can be difficult. This is especially true for rounds that have a lifespan of only 3 years. From what you can expect, .224 carries a little more than about .223. 80 and more.

Overall Practical: The .224 Valkyrie takes advantage of the .223 and dramatically expands its performance range. Archers of all ages can comfortably shoot Valkyrie without feeling frustrated. He was a proven competitor on PRS trucks. However, he will not be able to fully board until more bolt-action options are available. I think the market will catch up with this round.

3- 243 Winchester

History: .243 was introduced in 1955 and was designed as a sports and shooting rifle. It was a good option at the time for those who wanted long-distance performance with very low setbacks. At that time, this pattern was revolutionary. That's because the gap between the small and the fast warm mint shells was filled with a heavier, medium-sized game caliber. Athletes can use the rifles used for guinea pigs and coyotes, just like deer. .243 was also a good option for people living in countries that banned the use of military land (.308 Win / 7.62x51mm NATO).

First idea. This caliber flourished in the second half of the 20th century and has existed ever since. As interest in long-distance communities grew, one thing became clear. For best overall performance, the projectile weight should be in the 140 gram range. .243 is not fast enough to sustain long-range continuous flight. In addition, terminal performance at larger targets turned out to be weak at best (one of the main reasons .243 did not overtake the army).

Nose Speed: .243 Winchester has a wide MV range. From 3,025 fps (105 grain projectiles) to 4,058 fps (55 grain projectiles).

Ballistic Coefficient: 108 ELDMatch projectile for optimal LR performance. G1: 0.515, G7: 0.268.

Residual power: Snout: 2158 vt-lbs 500 m: 1 047 vt-lbs 1 000 m: 436 vt-lbs 1500 m: 222 vt-lbs

Transonic speed range: 1200 m @ 1104 fps Rebound condition: Like most calibers below 150 grain shells, rebound can be considered mild. One of the selling points when this round was introduced was the slight setback of the "Dia Pistol".

Cross-platform use: This caliber is a bit outdated, so the latest tactical platforms do not maintain the .243 product line. Most .243 rifles are stored in old wooden sporting goods such as the Winchester Model 70 and the old Remington 700.

Ammunition Availability: .243 Winchester is still a viable option for most East Coast and Midwest prairie dogs. I think every Wal-Mart in America has .243 Winchester. Truck makers are still making high-end wraps at .243.

Take a life. Very bad when firing light bullets, not as good as firing heavy shells. The .243 barrel life ranges from 1,500 to 3,000 laps. Overall Practical-In general, if you're new to the LR community and your family has .243 heirloom, and this is it, call back and work on the basics. The .243 is a great starter rifle due to its low recoil and ammo availability. It's also perfect for beginners and experienced hunters who want a great flatbed rifle that can catch guinea pigs and deer simply by changing ammo. As a serious LR shooter who demands terminal performance or wants the latest tactical builds, you're leaving .243 in the 20th century to which it belongs.

4- 6mm Creed Moore

History: 6mm Creedmoor, of course, may have something to do with my brother. 6.5 cm. The Outdoor Column writer wanted to write an article on how to design wild patterns. His favorite caliber at the time of shooting the LR competition was 6.5CM. He took the container, lowered it and loaded it with 0.243 (6 mm) shells. I wanted a lighter recoil pattern with the same performance, so the 6mm Creedmoor was born. The caliber has swept the LR community. Early pioneers were Ruger, GA Precision, Hornady and Savage.

First thought: Like other exciting new calibers designed specifically for the LR community, I know performance goes off the top shelf. The 6mm CM stands out in the PRS community for long-distance hunting. I'm curious how the price of such a system will go down and entry-level LR shooters will be available. I like the caliber offered on the high level AR-10 platform for gas rifle enthusiasts. I still think this pattern may be a bit on the wild side of the market (expensive for shooting and barrel burners).

Snout Speed: The standard shell weight for optimal 6CM performance is a 105 grain burger target VLD at 3,100fps.

Ballistic coefficient: 105 grain Berger VLD G1: 0.517 G7: 0.265

Residual power: Nozzle: 2,240 vt-lbs 500 m: 1,091 vt-lbs 1000 m: 457 vt-lbs 1500 m: 221 vt-lbs

Transonic speed range: 1250 m @ 1091fps.

Backflow condition: Very similar to the .243 Winchester. However, as the 6CM is available in more modern versions, devices like muzzle brakes and silencers (not found on most .243 rifles) will make the recoil experience even more enjoyable than the 6CM.

Multi-Platform Use - A big selling point of the 6CM is that since its inception and with the help of GA Precision, its use on the AR-10 platform has been immensely popular with PRS shooters.

Ammo Availability: Unsurprisingly, the 6mm Creedmoor is still a young bullet. Developed in 2017, most of the ammunition will come from reloading. That said, there are many commercial options, but the price will be much higher than that of standard cartridges. The average price per round will approach $ 2.00.

5- .300 Winchester Magnum

History: Winchester Magnum produced .300 in 1963 by Winchester itself. The goal is to design a married cartridge .338 Winchester Magnum and .375 H&H Magnum. Many other .30 magnum caliber cartridges were made at the time, but the .300 Winchester Magnum was only one of the lots establishing the test of time. To this day, .300WM is still a popular choice among long-distance hunters and military snipers.

First impression: This cartridge will always hold a special place in my heart. With the right rifle, .300WM can be a soft shot base. It hits hard and flies straight. Fall? The cost of guns and ammunition.

Original speed: 190gr SMK MV: 3 150fps

Well-coordinated: On top of the ball, G1: 0.539 G7: 0.276

Remaining power: Height: 4,186 ft-lbs. 500 m: 2,115 ft-lbs 1,000 m: 937 ft-lbs. 1,500 m: 426 ft-lbs.

Frequency: 1,300 to 1,116 fps.

Return mode: From brake muzzle and / or brake, .300WM can be as .308 Winchester. Without it, this cartridge should be old, more experienced than light. Cross-platform usage: There are a few AR-10s that can draw .300WM. Today, the main platform is the bolt (long-range) rifle.

Ammo Access: This cartridge has been around for some time. Ammunition can be found in many toy stores. The app for moving it is also fast. The cost per rider is $ 1.75.

Barrel Life: As with other magnum cartridges, the average barrel life is 1,500 to 2,000 rounds.

Overall quality: As a .300 WSM, this cartridge is best for long hunting. For an archer who wants to escape the rust on his family farm, this color is too much. Gorgeous crime with endless ballistic performance and a long-lost cost of barrel life.

Verdict: If you put a gun on my head, 6.5mm Creedmoor is generally the best long caliber. It's a choice on the ground. After writing down each of these parameters and checking each meter, I was able to come up with a much better lap than the 6.5CM in a particular category ... but it's better in almost every category. It's a product of natural selection and evolution ... the best features of some classic LR rounds have been integrated into one. Is it the fastest? No. Will it go further? No. Is it the most accurate? (Well, it depends mainly on the shooter.)
