308 ballistics by the inch

Obviously this is a different cartridge type, but also our 6mmBR barrel end length was 5 longer than Rifleshooter.coms .308 Win start length. SDs and ES were superior from the longer barrel, as was the sight picture. The U.S. militarys 7.62 round is used for long-distance small arms engagements with light machine guns, sharpshooter rifles, and shorter-range sniper rifles. The bottom picture is the first group I shot with the rifle, 5-shots, .785 including cold bore. How you use the data is entirely Is there a dramatic difference between the pressures created within a 7.62 NATO case and a .308 Winchester case? While we have went to great lengths to make sure that it's as accurate as possible this rendering should not be used to generate specs for casings. I got the longest blank I could and went from there. Based on my limited experience with the 330 BLK and 7.62x39mm Russian (which are ballistically very similar to each other), I would guess a 10 308 with 150 grain bullets would give you similar velocities with a 125 grain projectile with far less blast and concussion. At 10-inches, muzzle velocity hasn't reached its peak. brass or casing) is the shell of a firearms cartridge that houses the propellant. In fact the .308 Winchester 165gr bullet is traveling faster at 1000 yards than the .223 or 7.62x39mm at just 500 yds. This means that when you pull the trigger, 7.6251 brass expands less outwardly but farther toward the chamber. Much Different Results with 6mmBR and a Longer Barrel We stopped at 500 yards, but I had some legit 2.5 500 yard 5 shot groups. Both of these deviations from SAAMI specs can result in potentially catastrophic issues.

I use a Forster Match Rife Headspace Gauge Kit. Out of the 4 recording I made, only two frames contained muzzle flash. Coming out of the muzzle, it maintains speeds around 2,750 to 2,800 fps. The bolt action pistol with a 5 barrel (above). Although they share .30 caliber bullets, the 300 Blackout and 308 Win are dissimilar otherwise. I like it a lot. Yes, I do. It seems like the 7.62x39mm Russian performance is optimum at a 16 barrel length. One note: in every case with the T/C Encore the length of the barrel The 243 Win's muzzle velocity hinges on its bullet weight. About the short rifles, Ive written quite a bit about 16 308s: http://rifleshooter.com/2015/02/the-16-inch-308-winchester-bolt-action-rifle/. Super Short Precision Rifles: Is there such thing as a 16.5 .308 Tactical Bolt Action Rifle? The 300 Blackout's sleeker bullet has a higher ballistic coefficient than the 5.5645, but with less speed its trajectory invariably arcs more sharply. That works out to an average loss of 22.7 fps per inch. ga.src = ('https:' == document.location.protocol ? on each to just browse the charts, click on a given ammunition type listed in the header of each chart February 1, 2016 A Did it really hurt to shoot a short 308 pistol?

The vast majority of rifles, carbines, and pistols chambered in .308 Winchester can safely sling 7.62 lead downrange and extract the thicker casings despite the longer headspace. The U.S. Army lists the 7.62s effective range (and thus, the .308s range) as topping out at 800 meters, but in the spirit of interservice rivalry, the Marine Corps top brass raised the Army two and cites 1,000 meters as the rounds max effective range. If you have a modern .308 Win. That said, we wouldnt make a habit of it. The 7.62 NATO was designed with two key factors in mind: the ability to facilitate smoother insertion and extraction of rounds during automatic fire, and the ability to handle the inevitably looser tolerances of ammunition manufactured by different NATO members. Just ask Todd Hodnett. The cuts were made in one-inch intervals with a rotary saw. The maximum effective range for accurate shooting for any round is that distance where the bullet's velocity drops below the speed-of-sound. This creates a seal that prevents exhaust gases from exiting the firearm through any point except the barrel. var ga = document.createElement('script'); ga.type = 'text/javascript'; ga.async = true; data is provided purely for entertainment purposes - to better facilitate arguments He,he.

Once data was gathered for each cartridge at a given barrel length, the rifle was cleared and the bolt was removed. Compare the above rates of loss to those found in308 Winchester / 7.62x51mm NATO: Barrel Length versus Velocity (28 to 16.5), where the Winchester 147 grain FMJ averaged 24.6 feet/second per inch of barrel, IMI 150 grain FMJ averaged 22.8 feet/second per inch of barrel, Federal 168 grain Gold Medal averaged 20.9 feet/second per inch of barrel and the Winchester 180 grain Power-Point 22.5 feet/second per inch of barrel. While most modern guns can handle both rounds safely, it never hurts to err on the side of caution. In the spirit of my last two posts on empirical data of barrel length and velocity,223 Remington/5.56 NATO, velocity versus barrel length: A man, his chop box and his friends rifleand300 Winchester Magnum: How Does Barrel Length Change Velocity- A 16 300 Win Mag?, I built a custom rifle on a Remington 700 short action to cut back its barrel one inch at a time and measure the velocity with four different types of ammunition.

In308 Winchester / 7.62x51mm NATO: Barrel Length versus Velocity (28 to 16.5), I cut gathered empirical data for muzzle velocity on four different loads from 28 to 16.5. They were fairly close. When you pull the trigger on your M14, it starts a chain reaction. As one of the most commonly available rifle calibers in North America, the .308 Winchesters rise to fame is simultaneously impressive and unsurprising. These figures give this bullet a 4.4 out of 20 power rank using our algorithm. Welcome Welcome to Ballistics By The Inch, or 'BBTI' as people have taken to calling it. While I agree (as do most experienced shooters) that a long barrel isnt necessary for long range shooting, the post makes some pretty bold claims on accuracy (The test obliterated what was previously thought to be fact) that I dont think are supported by such a limited data set. That works out to an average loss of 22.7 fps per inch. The barrel was cut off using a cold saw. I think he may be misquoting his source.

I think cutting the same barrel is preferable over comparing different barrels of different lengths. 0. The initial testing was done in 2008 and tested the velocity of 13 common handgun cartridges as it related to firearm barrel length. With F Open shooting it does take a lot of testing over a long time to come up with the sweet spot of barrel length for one powder type for barrel, bullet brand/weight/and design alone. This was an average decrease of 81.7 feet/second per inch of barrel length. Thank you. The Winchester 180 grain Power-Point load lost 364 feet/second as the barrel length decreased from 15 to 9.

And thanks to our spouses, who were not just tolerant but enthusiastically supportive The 6.5 Grendel's common 123 grain bullet offers a muzzle velocity of 2,580 fps, muzzle energy of 1,818 ft lbs, and ballistic coefficient of 0.506. While the external dimensions of both 7.6251 and .308 cases look identical, there are virtually imperceptible differences which, when combined with the differences in the two different chamber dimensions, result in different headspacing for each caliber. Click Besides the time, I havent noticed any burrs (real or imagined) left by the saw affecting the velocity of the bullets. The small sample size is always an issue. The barrel did heat up during firing. This resulted in a velocity loss of 106 feet/second. (function() { When you confine that chemical reaction into a space half the size of a pen cap with only one weak point, the base of the bullet, that intense pressure has the ability to propel a chunk of lead roughly the size of your pinky nail up to a mile with deadly effect. Last week I found out Cerakote has a color called USMC Red. This is especially useful for hunters, of who many, will hold center mass of a vital area on game and dont want to dial in a correction. This allows it to keep a supersonic muzzle velocity at 1,000 yards. Bill Marr And if you think you could do better, feel free to spend the money I cant find the source document and data set (he does have some nice graphs), but it seems the author is trying show you dont need a long barrel for long range shooting.

The .308 Winchester round shoots pretty flat out to 200 yards when it starts to drop. The short barrels gas out pretty quickly. No guessing, no models, no arbitrary numbers. This chart shows velocity changes for all four ammo varieties: Summary of Findings: A crown that does not run true to the bore can not only destabilize the projectile as it leaves the barrel, but also causes []. real world guns. Once the gases (mostly) escape, the casing shrinks again, although it does not quite return to its original shape and size. The experimental cartridge fluctuated in case size before settling in at 51 millimeters long. Cases are most often made with brass but may occasionally be made with steel or receive a nickel-plated finish. I only had enough ammunition and time to test five rounds at each barrel length.

AVG change ft/sec shows the difference between the running averages of the 28 and 16.5 barrels. Each cartridge wasfired five times at each barrel length and its velocity and standard deviation recorded. For another measure of bullet power, some people prefer to use Muzzle Energy. (function() { Since the 308 Winchesteris a popular hunting cartridge, I worked out the maximum point-blank range (MPBR, sometimes referred to as maximum point blank zero) for each barrel length with the given load assuming a 8 vital area. In 1952, Winchester beat the Army at its own game and launched the new .308 Winchester to the civilian market, a good two years before the 7.6251 saw the Pentagons official green light. Comparing the data from the 30 shot strings (28 2824 and 16.5 2555) to the 5 shot strings (28 2823 and 16.5 2561) I found a loss of 269 ft/sec (23.4 ft/sec per inch) as the barrel was cut.
