308 ballistics by the inch

Try these too.. 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. Please seeModular Driven Technologies (MDT) LSS Chassis Review. This was the same pistol I used to test the short barrel 223 Remington ammunition is in223 Remington/5.56mm NATO Barrel length versus Velocity- Short Barrels- 6 to 14 inches. A summary of the data for all four cartridges is provided below. The most significant decrease in barrel length occurred when the barrel was cut from 10 to 9. My lathe is a two hour round trip to the range. I bought a quart. This was with Varget powder. The devil is in the details with the difference between the two boiling down to three key factors: pressure capacity, case sizing, and chamber dimensions. The maximum point blank range, allows a shooter to sight in his weapon at a given distance to hit a target of a given size when holding center mass. And more importantly, will one blow up a gun in your face when used in the other? This could have some potentially expensive consequences. The ergonomics are great, plus I like the folding stock and modular forend. Why you ask? This is how semi-auto No guessing, no models, no arbitrary numbers. Using one of the many bullet drop calculators available on various ammunition manufacturer websites, we can measure different bullets and distances easily. I think the value of this data is worth the time, effort and expense. Ive been beating on the 510 and 517 for a while. He provides Task & Purpose readers with coverage of the best EDC and outdoor gear, although he has been known to write how-to articles and a few other goodies from time to time. This weight is more appropriate for whitetail deer and other small-medium sized game. Are 7.62 NATO (a.k.a. While this may sound contradictory, it isnt. Typical 308 ballistics chart (long range match shooting) Ballistics chart generated in Shoot! Like the 5.56 versus .223 comparison, understanding the differences between 7.6251 NATO and .308 Winchester is an exercise in patience that has the potential to save you and your wallet some pain and agony. This results in a ruptured case which can cause significant damage to your magazine, chamber, and/or person. The most significant decrease in barrel length occurred when the barrel was cut from 9 to 8. Yes, it did. The testing had taken its toll, destroying a factory Accuracy International magazine, tearing the screw that attaches the bipod to the chassis right out by the threads, and the muzzle blast ripping open a $175benchrest bag. Troubleshooting seized ejectors. Great test ! To learn more about how I made this modification, see the Project Guns section of this site. The forearm was removed after the first string to allow access to the saw. The IMI Samson 150 grain FMJ is a 7.62x51mm NATO spec cartridge.

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. site designed and maintained by Coeurbois Graphic Design. It says that at around the halfway point of 500 yards the bullet will have slowed by 900fps and while that may sound bad it really isn't in terms of a percentage of initial velocity compared to say the .223 Remington (would be 1481fps from initial 3214fps) or the 7.62x39mm (would be 1066fps from initial 2349fps). According to multiple non-scientific studies, the average .308 case weighs in around 160 to 170 grains each, while 7.62 brass usually comes in at over 180 grains apiece. NTX 83176 2050 1450 1070 145 72 39 -1 5 0 -156 SeeMagnetoSpeed V3 versus Oehler 35P: Chronograph comparison and review. If your .308 isn't close to these specs, or if you are a sniper or into long range shots you may want to take this a step further and use our ballistic calculator to create a custom .308 ballistic chart to take into account variances. The first number is the value of this cartridge, and the last number is the value of the most powerful round in our bullet database. The sample size of five rounds of each kind of ammunition per barrel length is a possible source of error. It will a produce a line graph showing the bullet drop and flight path of the bullet. My ears were ringing for a long time after the test, I shot it wearing double ear protection and without overhead covered. I had a 34 Border on my Palma rifle for a time. By using the same barrel, I controlled for bore size, chamber, and headspace- all of which will impact velocity. Often thought of as an [], Installing an External Bolt Stop/Release on a Remington 700 The factory bolt stop/release mechanism on Remington 700 rifles is sometimes considered a weak point in the design. My 22 308 Winchester (above) is my favorite rifle to shoot. 308 Winchester/ 7.62x51mm NATO Short barrel length and velocity- A six inch 308 bolt gun? At each cut length, velocity was measured with a Magnetospeed chronograph. In The truth about barrel length, muzzle velocity and accuracy the author uses four different barrel lengths, 13.5, 16, 18 and 26.5, and eight different cartridges. })(); To comment on a post, click Post Title or "Comment" Link. Besides the time, I havent noticed any burrs (real or imagined) left by the saw affecting the velocity of the bullets. and do the work and publish your own results. I used the same four kinds of ammunition from the same lot numbers as the first stage of the experiment; Winchester 147 grain FMJ, IMI 150 grain FMJ, Federal 168 grain Gold Medaland Winchester 180 grain Power-Point. In addition to riding on the back of the 7.62 NATOs short-lived military career, the .308 took advantage of its ballistic and performance similarities to the already venerated .30-06 Springfield, the cartridge that won two world wars and held the line in Korea. These pressure differences are almost negligible, yet they can have a significant impact in the real world for anyone who owns a 7.62-chambered firearm or who likes to reload their own ammo. 30-30 Ballistics Chart & Coefficient. Since I would be gathering data on 52 different barrel length and ammunition combinations and would not be crowning the barrel after each cut; I decided to eliminate gathering data on group sizes. The bolt action pistol with a 5 barrel (above). We (well, Jim K, So while more reliable results will be obtained with a larger sample size, the data generated from a smaller sample is still of some use (provided it doesnt contain an outlier- which is why I dont know of anyone using data from single shots). Flawlessly. ALL Bulletin content is copyrighted, 2023 AccurateShooter.com. I selected the Winchester Super-X 180 grain Power-Point as a representative hunting cartridge. Yes, I guess I did. The small sample size is always an issue. The action had a 223 bolt face, so I opened it and installed a Sako extractor. Once data was gathered for each cartridge at a given barrel length, the rifle was cleared and the bolt was removed. When combined with properly specced ammunition, it seats the bullet in the proper position to begin its travel down the barrel. The initial testing was done in 2008 and tested the velocity of 13 common handgun cartridges as it related to firearm barrel length. My calculations assume a 1.75 sight over bore height. 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. real world guns. A JHP: Cor Bon 225 gr. A. ATTENTION: Effective Sept 1, 2020, the BBTI Project is in "Archive Status." No complaints, no problems. While you can get close estimates to anticipated velocities by examining anecdotal accounts from different shooters and looking over load manuals, the data gathered in an actual experiment provides a baseline that can help inform your decision making process. var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(ga, s); Super-X Hollow Point has stated muzzle velocity of 2390 fps. mostly) paid for everything ourselves, and we did not receive any kind of sponsorship At 300 yards it has dropped around 13 inches, and at 500 yards it's just under 60 inches (5 feet). These graphs assume a 1.75 height of the optic over the bore and weather conditions of 59F. There are plenty of good sources of information on this topic. Over the past few years, Rifleshooter.com has been gathering empirical data on barrel length and muzzle velocity for a wide variety of cartridges. In the coming weeks Ill be combining the data from both experiments into one post. The .308 Winchester round shoots pretty flat out to 200 yards when it starts to drop. 7.62 NATO (a.k.a., 7.62x51mm) and .308 Winchester are two very common rifle cartridges commonly used by U.S. service members and civilians. Looking for the perfect accessories to accompany your new .308 or 7.6251 rifle? Last week I found out Cerakote has a color called USMC Red. Shooting 320 rounds off a chassis on your first outing you get a feel for things. This includes detailed charts with inch-by-inch velocity numbers, multiple line charts, and complete data sets for each type of ammo. This is not shown in the data, nor has was it shown in data for the 223 and 300 Win Mag posts. The Federal shows a fairly straight line. The headspace on this pistol measured 1.630 (SAAMI minimum), this was .003 less that when the barrel was installed on the rifle (1.633). When the U.S. Army began developing the 7.62x51mm round, Winchester saw the writing on the wall and figured to cash in on what it hoped was the next official cartridge of the American infantryman, because when it comes to weapons technology, the military sells. The .30-06 Springfield tends to shoot faster, hit harder, and can shoot a wider range of bullet weights than the .308 Winchester. Fear not. 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. By This project, and all of its results, is only our fault. .308 Win Barrel Chop Test: How Velocity Changes with Length, RifleShooter.com .308 Win Barrel Cut-Down Velocity Test, .308 Win Velocity vs. Barrel Length 28 to 16.5 Cut-Down Test, Surprising Results in .223 Rem Barrel Cut-Down Velocity Test, Barrel Length and Velocity in a .223 Rem Barrel Cut-Down Test, http://rifleshooter.com/wp-content/uploads/2015/01/custom-16.5-rem-700-308.jpg.

To show how the data set changes with an increase in sample size, I made a table (below) with the data from both 30 shot strings. Velocity was about 10 FPS below that of my 30 Border. The cuts were made in one-inch intervals with a rotary saw. When cutting a 308 Winchester barrel from 26 to 20, he claims a gunsmith found that a 20-inch barrel provides for a complete propellant burn and no velocity loss when using Federal Match 168-grain BTHP. I think data sets are great. 308 Winchester Barrel Length and Velocity: Winchester 147 grain FMJ, 7.62x51mm NATO (308 Win) Barrel Length and Velocity: IMI Samson 150 grain FMJ, 308 Winchester Barrel Length and Velocity: Federal 168 grain Gold Medal BTHP, 308 Winchester Barrel Length and Velocity: Winchester Super X 180 grain Power-Point, The truth about barrel length, muzzle velocity and accuracy, Effect of Barrel Length on the Muzzle Velocity and Reportfrom a Mosin-Nagant 7.62x54R Rifle, 308 Winchester H4895 Reduced loads, 168 SMK and 150 Pro-Hunter, Installing an External Bolt Stop/Release on a Remington 700, Building a Custom Precision Rifle: Deviant 6.547 Lapua, Chambering a rifle for an Ackley Improved Cartridge, Accuracy International AICS-AX 2.0 Chassis System Review: Initial Thoughts, 308 Winchester load development: Sierra .308 195 gr. It fires a .312-inch-diameter bullet as opposed to a .308-inch-diameter bullet and operates at 45,000 psi as opposed to 40,000. When you switch this out with a .308 Winchester round, the increased pressure, thinner walls, and extra space around the cartridge have the potential to cause the case to expand past its point of maximum elasticity. Maybe he meant negligible? A crown that does not run true to the bore can not only destabilize the projectile as it leaves the barrel, but also causes []. .32 Winchester Special, .308 Winchester (7.62mm NATO), .38-55 Winchester, .243 Winchester, .300 Remington Short Action Ultra Magnum, .25-35 Winchester, 7.82mm (.308) Lazzeroni Patriot, .260 Remington, .307 Winchester, 6.17mm (.243) Lazzeroni Spitfire, .356 Winchester, 6.71mm (.264) Lazzeroni Phantom, .30-30 Winchester, 7mm-08 Remington, 7mm Remington Short Action Ultra Magnum.

Get the latest in military news, entertainment and gear in your inbox daily. The 7.62x51 NATO is a superior round to the .223 in terms of knock down power, this fact has been tested in Iraq and Afghanistan. Much Different Results with 6mmBR and a Longer Barrel At each barrel length, the rifle was fired from a front rest with rear bags, with five rounds of each type of ammunition. Ballistics by the Inch (often called BBTI) was a project to test the performance characteristics of a variety of common handgun calibers/cartridges. Thanks for the kinds words about the 308 and 300 Win barrel length posts. At each barrel length, the rifle was fired from a front rest with rear bags, with five rounds of each type of ammunition. The chops tests ranged in barrel length from 18" down to 3". contrast, the chamber pressure of 5.56 NATO is only roughly 75% of that, at about 60,000 PSI, while 6.5 Creedmoor and .308 Win have only slightly higher chamber pressures at 62,000 PSI. Looking for a two-minute summary of the differences between 7.62x51mm NATO and .308 Winchester? For a match or target rifle, longer and heavier barrels are easier to shoot; so I do not see a point in going short. Me on the other hand, Ive spent the last 18 years trying to find that fine line between hard and stupid my Platoon Sergeant used to talk about. Yes, I did for the 223 post. IMI 150 grain FMJ 7.62x51m NATO data was gathered down to a 6 barrel length. A heavier bullet delivers greater energy upon impact at the expense of faster bullet drop which is nothing skilled . This chart shows velocity changes for all four ammo varieties: Summary of Findings: The average velocity loss per inch, for all four ammo types combined, was 22.7 FPS. 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. Do a search for .308 and you will find similar results, albeit with fewer references to 7.62. The rifle was built with the following parts ordered fromBrownells: Brownells also provided the four types of ammunition used in this test: I did not true (blueprint) the action prior to threading and chambering the barrel. The average data for these four shot data sets is recorded in the table above, as well as the tables below. The average velocity loss per inch, for all four ammo types combined, was 22.7 FPS. The latter has nearly twice the propellant, and is therefore better able to fell very distant game. Acknowledgements. Since we would be gathering data on 52 different barrel length and ammunition combinations and would not be crowning the barrel after each cut, we decided to eliminate gathering data on group sizes. Average velocity loss from 28 to 16.5, was 24.6 ft/sec per inch for the Winchester 147 grain FMJ, 22.8 ft/sec per inch for the IMI Samson 150 grain FMJ, 20.9 ft/sec for the Federal Gold Medal 168 grain BTHP per inch, and 22.5 ft/sec per inch for the Winchester Super-X 180 grain Power-Point. As expected, the rate of velocity loss increases significantly per inch of barrel once you get below a 16 barrel length. Average velocity and standard deviation were logged for each round. Cutting the barrel from 28 to 16.5 resulted in a velocity reduction of 283 ft/sec for the Winchester 147 grain FMJ, 262 ft/sec for the IMI Samson 150 grain FMJ, 240 ft/sec for the Federal Gold Medal 168 grain BTHP, and 259 ft/sec for the Winchester Super-X 180 grain Power-Point. Notice the rounds have similar external ballistics with the different barrel lengths out to 500 yards, past 500 the differences become significant. The cartridge case (a.k.a. was measured from the end of the barrel back to the breech face. Velocity Boundaries (Feet per Second) of: 1740 1460 1460 1460. Once it reaches 500 yards, it has slowed but it's still maintaining . All shooting was done from a bench, with a Sinclair rest and rear bag.

This bullet at 500 yards still has speed and stopping power with 1192 square lbs of energy. So it's not a shocker that the .308 would be a good cartridge. With barrels, one wonders Can a little more length provide a meaningful velocity gain? To answer that question, Rifleshooter.com performed an interesting test, cutting a .308 Win barrel from 28 all the way down to 16.5. I used my iPhone to record a couple shots being fired in slow motion.

It seems like the 7.62x39mm Russian performance is optimum at a 16 barrel length. With a barrel reduction from 28 to 16.5, the average speed loss of the four types of .308 ammo was 261 fps total. Average velocity and standard deviation were logged for each round. Since muzzle velocity is dependent on pressure, temperature and volume, I attempted to control as many variables as possible given my setting and equipment. calibers/cartridges + numbers. Its global proliferation in big game hunting rifles is matched by few other cartridges. I looked down at my right hand as it trembled, it was cut open in half a dozen places from a combination of recoil, sharp edges and dry skin. The rifle with a shorter barrel was louder. This means that when firing a .308 round in a 7.62 chamber, the .308 brass will stretch beyond its intended elastic range. 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. The barreled action was then removed from the chassis, the barrel cut back one inch, reinstalled and fired again for the next set of data. I fired 30 rounds of IMI Samson 150 grain FMJ at 28 and 16.5 and recorded the results. I selected Federal 190 grain Gold Medal ammunition for this test. This resulted in a velocity loss of 94 feet/second. This means throwing .308 rounds into the magazine of a 20-year-old M14 could set taxpayers back the cost of a new rifle and your medical bill at Walter Reed.
