.308, .30-06, .223 Sniper Rifles

Reach out and Touch Someone

Sniper rifles are designed as single shot weapons for long range. Even in the urban field, this kind of attack is awesome.  Who is able to locate a enemy lying at 500 meters from him ? The most difficult thing, when making a long range attack, is to find a good place to shoot from. That is one which provides a good point of view, and where one can prepare his weapon and wait for his victim without being disturbed. Various equipment (smartlink, scope, laser-assisted aim, computer-assisted aim, bipod, suppressor...) allow maximum accuracy and discretion for modern snipers.


.300 Winchester Magnum

The 300 is an outstanding sniping round for military applications! But as you might imagine, it offers a lot of power and penetration, which limits its role in Law Enforcement. I am aware that the Secret Service uses the .300, but they're situation is rare, they don't have to be too concerned with hostages. They just need to insure that the possible assassin is stopped, and the .300 is a good caliber to do that. The .300 is also a great round for going through media in order to hit the target. The .300 is very capable of extending out past 1000 meters reliably, reaching 1200meters on a nice calm day without much effort. One big criticism of the .300 is the amount of recoil that the round produces. To be honest, it really does punish the shooter, making long sessions at the range a very grueling situation. If you are not careful, you can easily develop a flinch in your shooting cycle, this could be very bad. But with proper training, and a gradual migration into the .300, you can overcome this problem.

Recommendation: The .300 gets my highest recommendation for military use.  If you could find a suitable round that limits over-penetration, the .300 could be a very flexible caliber, offering good armor penetration with the change of ammo.

Military Applications

Note: The Federal Match .300 was chosen for my military round, it�s a great round and serves admirably, the 190gr Sierra Match King has a really nice Ballistic Coefficient.

7.62x51mm NATO (.308 Win)

The .308 is by far the most popular sniping round, and for good reason. The .308 is not punishing to shoot, has excellent terminal ballistics, behaves predictably in the wind, and is consistent. While there are quite a few rounds that outperform the .308 in ballistics, there are few, if any, that perform as consistently as the .308. And consistency is accuracy. The .30 cal bullet has long been a great performer, and is very popular which leads to more research with the .30 then with other calibers. While the .308 may over penetrate in some cases (especially with M118) the .308 is still used in the majority of the Law Enforcement agencies out there. It is accepted that if you do your job and put the bullet where it counts, you can count on the .308 to do its job and incapacitate the target. The US Army preaches an 800 meter maximum effective range for the .308, the USMC preaches a 1000 meter max effective range. While I have made hits at 1000 meters and beyond with the .308, I would have to agree with the Army and say that 800 meters is the limit for RELIABLE hits. After that the .308 is dropping like a rock and is inconsistent. As an all around sniping round that works great for both Law Enforcement and military sniping, the .308 is hard to beat!

Recommendation: The .308 is acceptable for both military and Law Enforcement use, and is very capable of 800 meter hits on a human size target. If there is a need to reach beyond 800 meters, I recommend something with more oomph then the .308. If you are a Law Enforcement sharpshooter, keep in mind the penetrating power of the .308, especially with full metal jacket rounds (Like the M118).

 Military Applications

Note: I have listed the M118 (The current military sniping round) and also the Federal 175gr Match Ammo, they are both suitable for military sniping. The US Armed forces is currently in a transition to M118LR, which fires a 175gr Sierra Match King bullet, exactly like the Federal Match ammo, but it fires it 20 fps slower at 2580fps. The Federal Match 168gr is also included as the standard.

7.62x63mm (.30-06 Springfield)

The -06 served as the United States primary sniper round from WWI up until sniper rifles were standardized during the later part of the Vietnam conflict. The -06 offers good ballistics and served as an outstanding sniper round. While its purpose might be limited in the Law Enforcement arena, due to possible over penetration, but with the selection of the right ammo, the -06 would serve as a stellar round in a Law Enforcement situation. There is a shortage of sniper grade weapons in the .30-06, which I have never understood why. The -06 falls in-between the .308 and the .300. and there has always been match grade ammo produced by Federal. I personally think this is the ideal military sniping caliber, it offers better ballistics than the .308, but doesn't punish the shooter like the .300.

Recommendations: I recommend the .30-06 highly for military applications, but I am a little reluctant to recommend it for Law Enforcement use, unless you take the time to research and find a good, rapidly expanding round.

Military Applications

Note: I have chosen the Federal Gold Medal Match .30-06 for military use. It is more then adequate, but I really wish that they would load the 175gr at 2700fps, this would really be a good round, and it would be any easy change, its all done with the .308.

5.56x45mm NATO (.223 Rem)

 The .223 is used for law enforcement applications, largely because some agencies fear the over penetration of the .308 round in hostage type situations. The .223 generally splinters on impact, allowing almost no excess penetration that could possibly hit innocents, such as hostages. But with this fragmentation and lack of penetration comes a necessity for more precise shot placement, leaving almost no room for error. The .223 has a small temporary wound channel (Stretch cavity), requiring almost a direct hit on the spinal stem in order to get "lights out" on a target. The lighter .223 bullet is very susceptible to the effects of wind, which really limits its long range potential. While it is possible to achieve acceptable accuracy at 600 meters on a calm day, it is to risky on the windy days to really consider this round for military sniping purposes. Due to the lack of penetration and lack of energy, the .223 should only be used in very rare circumstances and only on head shots. There is more then one instance when a target has been shot with a perfectly placed center mass shot, and it failed to incapacitate him.

Note: In order to stabilize the 69-gr. Bullets and heavier, the twist on the rifle barrel needs to be at least 1:8"

Recommendation: only use the .223 within 100 meters and only take head shots if at all possible. If the .223 is all that your unit has in the way of a sniper rifle, be sure to keep in mind the limitations of the round.

 

Ballistics: Some possible rounds and their ballistics have been listed below.

The M21 is essentially a modified M14 National Match rifle. The earlier versions (XM21) had a specially selected walnut stock, but this changed with the M21 to a fiberglass stock, often camouflaged. The XM21 began to be fielded in the second half of 1969 and remained the U.S. Army's primary Sniper Weapon System until it began to be replaced by the M24 SWS in 1988. Some National Guard units and even a few active duty units (The OPFOR at JRTC for example) still use the M21. The M21 is a very practical sniper weapon maintaining acceptable accuracy out to about 700 meters. Besides the problem that it is semi-auto and sends brass flying, the M21 was, and still is, a very capable military sniper rifle. The 10th SFG, in conjunction with the U.S. Navy SEALs has developed an improved version of the M21 known as the M25. The M25 was designed out of a need for a semi auto sniper rifle, and it was the weapon of choice for SEAL snipers during Desert Storm. The M21 holds a dear spot in many U.S. Army snipers hearts (me included), and rightfully so.

The M25/XM25 is a joint venture sniper rifle, built for both the US Army Special Forces and the US Navy SEALs. It was orginally developed by the 10th SFG base at Ft. Devens in response to a requirement for a match grade M14 for Special Forces sniper teams. USSOCCOM was dubbing the rifle the "Light Sniper Rifle", and its also known as the "Sniper Security System" and "Product Improved M21".

The M25 is similar to the M21 in many regards, its a National Match M14 glass bedded in a McMillan fiberglass stock, uses a special gas piston, a National Match spring guide and a BPT (Brookfield Precision Tool) Advanced Scope Mounting System. Most rifles use the B&L 10x Tactical scope. Some of the Army rifles use some of the Leupold Ultra MK4 series of scopes. (Both the M3 and M1), and the Navy rifles have been seen with Leupolds also (MK4s and VariX-III LR M3s). Ops Inc suppressors have also been used on some of the rifles.

The rifle has been referenced as both the M25 and XM25 in US Navy and US Army docs, so I guess the rifle has two official nomenclatures. The M25 is NOT a replacement rifle for the M24, it was requested by the USSOCCOM to fill a specific need, and it served extremely well in the Persian Gulf war. The rifle is still considered a "transitional system" but as far as I know there is no development being done on a new semi-auto sniper rifle for SF.

DESCRIPTIONS

DPMS Model 500 +0 x20 60m 1 20 $1000/20 3kg 4 5.56x45mm

The Defense Procurement Manufacturing Service M500 is another combat rifle upgraded and heavily modified to fit the sniper role. The PS500, based on the AR15/M16 frame, has been given a free-floating match-grade heavy barrel, integral bipod as well as an available tripod in the buttstock. The barrel is also designed to accept any of a number of compatible suppressors. As with most upgrade-type rifles, the PS500 retains its burst-fire capabilities. Shown with variable 3-12X tactical scope (Sniper System capable of 2X range, no peripheral vision penalties), that is an available option for an additional $1000.

 

Mitchell 2257 +0 x18 60m 0 25 $600/30 2.5kg 3 5.7x30mm

The Mitchell 2206, unlike many of the other rifles in this category, is designed for comparatively close-in work where over penetration is a potential issue. Chambered for the .22 Remington Jet cartridge (5.7x30mm), the weapon has lines very similar to the common M16, but is substantially more compact.

 

Ruger 1006 & 1006S +0 x20 60m 0 5 $1000 2.5kg 3 6x48mm

The Ruger 1006 is a semi-automatic sniper rifle chambered for the 6x48mm round, and fired from an exceptionally heavy bull barrel. The 1006S (S for Suppressed, pictured. x18 BR30m) variant has an integral suppressor mounted, and like the Mitchell 2206, is designed for close-in sniper work. Both the 1006 and 1006S have an integral bipod as standard.

 

SIG 550 Sniper +0 x20 60m 1 20 $800/20 6kg 4 5.56x45mm

The SIG 550 is fairly typical of 5.56mm sniper-upgraded assault rifles. A longer bull-barrel grants a slightly increased range and the addition of a telescopic sight and tripod allow highly accurate fire to just under a kilometer. Unfortunately, the 5.56mm round loses energy very rapidly beyond this range. The SIG 550 is also relatively overbuilt -- the original 550 Sniper weighed in at over 7kg (!), well above most sniper rifles chambered in 5.56x45mm (4-5kg).
