[I]n early 2002, soldiers of the 5th Special Forces Group (Abn), headed by MSG Steven Holland, received approval to initiate a Proof of Concept to develop a new capability that would increase incapacitation, lethality, and range over the existing 5.45x39mm, PRC 5.8x39mm, 7.62x39mm and 5.56x45mm NATO cartridges. This initiative was a grassroots effort aimed at providing better combat power for Special Operations Forces and soldiers of the Light Infantry, to include USMC MEU-SOC. This was the original programmatic evolution proposed for the SOPMOD Mk12 Special Purpose Rifle (SPR) system, the interim result of which was the fielding of the Mk262 77-grain ammunition, with a planned later transition to the Enhanced Rifle Cartridge (ERC) capability in a mid-bore 6.5mm, 6.8mm or 7mm caliber.First, we compare the 77gr Sierra MatchKing BTHP with cannelure against the 115gr Sierra MatchKing BTHP with cannelure in terms of drop, wind drift, retained velocity and retained energy. The results are graphed in Excel and produced below: 1/2.8-in Progressive-scan CMOS Sensor 2.8 mm Fixed Lens Option
These dimensions may be modified based on user equipment capability or fabrication criteria. A more robust pattern may be desired for wave soldering and is calculated by adding 0.2 mm to the 'Z'.. The ogive of a bullet is the curved portion of the projectile that is exposed outside the case. The ideal bullet shape includes as long a bullet ogive as possible, while keeping the shape as close to that of a Sears-Haack body as possible. Increasing the ogive length either increases the cartridge overall length or necessitates a decrease in case length (reducing its capacity, unless the case head diameter is increased). In terms of cartridge design within a given OAL, longer ogives come at the price of less case capacity and therefore lower muzzle velocity, but in general accepting this comes with the benefit of better velocity retention over distances beyond about a hundred meters.
kino8mm@ukr.net This means that – at best – the 6.8mm SPC round can accommodate projectiles with a similar ballistic shape to the M855 round. Improved projectile shapes – including some that would be compatible with the 5.56mm standard – are not compatible with the 6.8mm SPC cartridge when loaded to standard magazine lengths.

In fact, had the 6.8mm SPC been introduced in the 1930s or ’40s, or had it been introduced as a dedicated medium game round (a sort of latter-day .30-30 to the .223 Remington’s .25-35, perhaps), I would have never taken the time to write the above analysis. It is the round’s serious limitations in the role for which it was designed – as a designated marksman rifle cartridge – that has made me take a closer look at its capabilities versus the round it was intended to replace. And after that, I am still a bit puzzled by it.It’s worth examining the dimensions of 6.8mm round itself in detail. The cartridge case is based on the rimless .30 Remington, and uses the same extractor groove and rim dimensions, with a rim diameter of .422″ or approximately 10.7mm. It uses the same case taper and shoulder angle as the 5.56mm rifle cartridge, the beta angles of those being 0.5 and 23 degrees, respectively. The round has a maximum case length of 1.6864″, or 42.83mm. Its overall length is the same as 5.56mm, at 2.26″/57.4mm, though some magazines are advertised as offering overall lengths as long as 2.315″/58.8mm, and the purpose-built Six8 rifle from LWRC, which uses proprietary magazines, offers an overall length of 2.32″/58.9mm. The cartridge has a case capacity of between 34.8 and 36.9 grs H2O (2.255-2.391 ccs), 14-21% more than the 5.56x45mm. It uses standard .277″ diameter projectiles, although it is limited in its selection of those by the overall length. In general, though the projectile diameter is the same, the 6.8mm Remington requires totally new projectiles versus existing .270 caliber rounds.
What this analysis makes clear is that the theoretical limitations of the 6.8mm SPC have a very real impact on its ballistic performance. Despite being designed to improve the performance of SPR-type rifles to medium ranges, the 6.8mm SPC when loaded with Sierra projectiles offers no improvement over current 5.56mm Mk. 262 ammunition except in terms of raw energy provided at ranges below 300m. Even with the ballistically superior Hornady BTHP projectiles, the 6.8mm SPC sacrifices important characteristics such as drop, wind drift characteristics, and a longer maximum fragmentation range for an advantage in muzzle energy that becomes increasingly small as distances approach 500m.ƒ5.6, 1/15 s, ISO 400.

The only thing I'm not sure about is whether to pick a 9×7 mm F1 oval solitaire or a 8×6 F1 oval solitaire. I don't want it to be too costume-y or cocktail ring-y, if that makes sense. Compared to rounds like the 5.56mm or 7.62x51mm, the 6.8mm SPC has a poor relative capacity. This is the ratio of the case capacity to the cross-sectional area of the bore, and is an important predictor of performance. A ballistically ideal round propels a bullet with a high sectional density and high fineness ratio at high velocity. The relative capacity of the round is closely related to that round’s ability to propel high sectional density bullets at high velocities. A good example of this is given by comparing the 6.8mm SPC to the 5.56mm Mk. 262, with bullets of identical sectional density, using the simple Powley computer available at kwk.us:As far as I can see, the diffraction affects the image starting from ƒ8. However it’s barely noticeable, so if you need the depth of field from 0.5 m to infinity or just want more corner sharpness, the lens may be used at ƒ16.
Sârmă pentru sudură cu acoperire cupru (SV-08G2S-O), d. 0,8 mm. Sârmă zincată d. 2,4 mm To properly compare the two rounds, it will also be necessary to choose two different types of OTM projectiles in each caliber: Sierra’s tangent-ogive BTHP and Hornady’s secant-ogive BTHP. Ballistic coefficients for all four projectiles will be taken from the ballistic coefficient resource on my blog. In both cases, the Hornady secant-ogive projectiles give lower form factors and thus higher ballistic coefficients, due to their conforming more closely to the Sears-Haack body shape. Further, both lighter secant-ogive projectiles will be calculated with the same muzzle energy (and thus slightly higher velocity) than both tangent-ogive projectiles; this is representative of pulling a loaded tangent ogive bullet from the case and replacing it with a secant-ogive one.Several propellants were reviewed to provide improved powder performance, including Western Powder’s Ramshot, and submissions from Accuracy Arms and St. Marks Powder Company. These companies developed powders particularly for the 6.8mm Remington SPC cartridge, and will supply quantities of the chosen propellant for final assembly of ammunition by Remington. The Special Forces SPC team require that the powder used is to be manufactured in the United States, and contain an organic flash inhibitor to decrease muzzle flash in low light conditions. 8mm film scans We dedicate a DCS Xena 4K scanner to HD, 2K, 3K Overscan and 4K 8mm scans of the highest possible quality for each scan resolution Base quantity bulk quantity.

군용으로 6.8mm SPC는 그다지 성공하지 못했지만, 이후 미군 측에서 새로운 6.8mm 탄환을 NGSW 사업에 채택하면서 6.8mm가 미군의 새로운 제식 탄환 구경이 될 가능성이 열렸다 As previously mentioned, it is beyond the limitations of the Powley Computer to generate velocities for the Mk. 262 round due to its high pressure. Powley calculations are also not truly representative of the performance possible from the 6.8mm SPC round, due to Powley being limited only to older IMR-type propellants, where the 6.8mm SPC performs best with newer propellants such as H335. For these reasons, when examining the ballistics of both the Mk. 262 round and 6.8mm SPC, I will be using non-calculated, non-empirical velocity figures based on the common performance of the two rounds. While the velocities used are not taken from any particular sources (as it is very difficult to find a truly controlled evaluation of the two rounds), I have done my best to choose figures representative of the actual performance of the two rounds from 18″ barrels with Spec II or DMR chambers.This is further exacerbated by the 6.8mm’s restrictions on fineness ratios. The fineness ratio of a projectile is the ratio of its length to its diameter, and this is a factor in the projectile’s ballistic coefficient (typically, bullets with high fineness ratios have better ballistic coefficients). Because of the 6.8mm SPC’s wider projectile, accommodating higher fineness ratio bullets (such as M855A1-style lead-free projectiles) is more difficult, and more significantly reduces the case capacity of the round. This is closely related to the relative capacity of the round.

The 5.56mm M855 round has received considerable criticism for its terminal characteristics. Detractors point out that the round fails to fragment when the striking velocity is too low – such as when fired from a very short barrel or when the bullet has slowed down thanks to its relatively unimpressive ogive shape – or when the bullet strikes the target at a very low angle of attack.What's the best camera for shooting sports and action?

The settings used are reproduced below:That’s one reason why it’s extremely puzzling to me that one of the most popular 5.56mm replacements – and the round many think offers the military a commercial-off-the-shelf improvement in effectiveness – offers even less in these criteria than even M855. That round is the 6.8mm Remington Special Purpose Cartridge.
Is this the cheapest lens available with native Micro 4/3 mount? For $75 it cannot be beaten. If you pixel peep, you’re unlikely to be happy with it. However, the lens is small, light, pretty fun to use, costs less than toy lenses and Olympus body cap fisheye, and allows you to make great images as soon as you learn focusing.The 8mm f/3.5 HD Fisheye Lens with Removable Hood for Canon from Samyang gives you a 167° view with dramatic, exaggerated perspective when used with an APS-C camera, or a powerful circular image floating in the frame when used with a full frame digital camera or 35mm film camera. With hybrid aspherical lenses and multi-layer coating, you will produce sharply defined images with a minimum of flare and ghosting. The 8mm lens focuses as close as 12" (30.48 cm) from the lens. This version of the 8mm f/3.5 Fisheye lens comes with a removable lens hood that provides glare reduction and lens protection, but can be removed to offer an increased and unobstructed angle of view when shooting at full frame digital or 35mm.

The 6.8mm SPC round evidently puts much more stress on the rifle’s bolt than the 5.56mm round, which may cause the bolt to break sooner. For the 5.56mm round to produce as much bolt thrust, pressure would have to be increased to nearly 70,000 PSI. Therefore, the Mk. 262 Mod. 1 round, despite its very high maximum pressure of 68,000 PSI, actually puts less stress on a rifle bolt than the standard 55,000 PSI pressure 6.8mm SPC round. Since both rounds occupy comparable roles and both rounds were originally intended for the same platform (the Special Purpose Receiver, later Mk. 12 Special Purpose Rifle), it seems reasonable to therefore compare them directly against each other.

It is very curious to me that a round that was designed with an accurized designated marksman’s rifle in mind also features such a short ogive and low muzzle velocity. Typically, medium/long range precision weapons platforms place a premium on both the ballistic coefficient and velocity of the projectile, seeking to obtain as laser-like a trajectory and as high a retention of energy as possible. The 6.8mm SPC runs directly counter to this.

The assessment of the initial performance capabilities of the prototype cartridges, based on shortened commercial .30 Remington cases, was handed over to the USAMU Ammunition Section, headed by Troy Lawton. Industry involvement to consider this project at no cost to the government was championed by Sean Dwyer at Remington, who stated that Remington wanted to do their part on the Global War on Terrorism, and provide production capability for the ammunition, which would be developed and manufactured by Remington using bullets provided by Sierra and Hornady.It’s therefore useful to be able to quantify this additional factor of pressure in some way. While it is not generally used in the relevant literature, I have chosen the term “internal specific energy”. To calculate this, take the relative capacity value and multiply it by the maximum pressure (giving units of lbf/in in English, or N/cm in Metric). This value is a hint only, as total work performed on the bullet is only roughly represented by the maximum pressure; for example, a round with slower-burning propellant may give higher velocities with a given bullet than one with faster-burning propellant, despite both having the same maximum pressure. It’s therefore wise to use this quantity only as a guide for sound cartridge design. Смотри video--02-05-2a9e09f8b606acfe1bc23c63d329d9ada17198799cdf2adbf8d8878db0cfc7f8-V[1] просмотров видео 6819..
