Brian Smyth site designed and maintained by Coeurbois Graphic Design. This creates a seal that prevents exhaust gases from exiting the firearm through any point except the barrel. The testers observed: The Berger Reloading manual says for the 308 Winchester, muzzle velocity will increase (or decrease) by approximately 20 fps per inch from a standard 24 barrel., How the Test Was Done I tried to select a cross section of cartridges that would be of interest to a wide variety of shooters. numbers. Headspace was measured at 1.633+ (.003 over minimum). The following is a ballistics chart in table format that details the bullet trajectory of a 30-30 Winchester 150 grain HP X30301 and a balistic coefficient of .218. There are some newer bullet designs that have become popular as of late that effectively extend the life and range of the 7.62x51mm NATO/308 Winchester even further. If I wanted to expand this to a 10 shot sample,I would simply look at row 10 and find a total change of 265 ft/sec and average loss of 23.0 ft/sec per inch of barrel. Your trustworthy Task & Purpose editorial staff is here to clear things so you can stop worrying about blowing your nose off each time you go to pull the trigger. the cylinder gap. Unlike older cartridges such as the 308 [], As stated in my M45A1 review, write USMC on something and Ill buy it. The .327 Fed. Take this into consideration when comparing calibers using our I actually had this happen on two different mags. Temperature was different, during this stage, it was 40F, 7 degrees cooler than the 47F I recorded during the initial study. 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. I used my iPhone to record a couple shots being fired in slow motion. Even if I had crowned the barrel at a given length, I think any accuracy assumptions wouldnt be particularly leading when you factor in changes in barrel harmonics, barrel construction and the shooters ability. Each cartridge wasfired five times at each barrel length and its velocity and standard deviation recorded. .277 Fury has a -41 inch drop at 500 yards . Ive been beating on the 510 and 517 for a while. Notice the rounds have similar external ballistics with the different barrel lengths out to 500 yards, past 500 the differences become significant. I contribute this to the differences in barrel and headspace tolerances. These seem much more durable over the long run. This is a very useful test is youre thinking about building a .308 Win hunting rifle, or perhaps thinking of going shorter for your F-TR rifle to save weight. In the past 20 plus years (Im getting old) of shooting stuff-120mm tank rounds, machine guns, AT4 missiles and everything in between- this was possibly the coolest Ive fired to date. We'd like to personally and specifically thank Pat Childs at Fin & Feather in Iowa City, as he not only helped get most of our The 308 Winchester centerfire cartridge has an average fps of 2681 (average made by adding and diving all bullets in our db), average grain is 164 (they don't make 164 gr this is just the average), and has an average energy of 2617. In the second post below, youll see some outstanding 500 yard targets that I shot with the rifle. Articles may contain affiliate links which enable us to share in the revenue of any purchases made. Stay safe, yall! 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. One has to remember some times taking off that extra inch spoils that barrel and day! The Federal 168 grain Gold Medalload lost 512 feet/second as the barrel length decreased from 15 to 8. Do you see any use for a 10 308 Winchester? 0. Trajectory for Custom .308 165 TGK #4667 AMMO at 2680 Feet per Second.

Is the reverse possible? The .308 just lacks the horsepower for truly long-range shooting. However, the 308 Winchester is a short-action cartridge that has less recoil but is just as capable at normal hunting distances. Are 7.62 NATO (a.k.a. This was noticeable from 19 inches and below. Powder burn rates can also make a difference. 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. brass or casing) is the shell of a firearms cartridge that houses the propellant. Compare the above rates of loss to those found in 308 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 What are possible sources of error in your experiment? The brand new, factory AI AICS magazine also flew apart as few times. This is how semi-auto Super easy to install and remove the action from the stock. Velocity loss can be more extreme with shorter barrel lengths (and bigger cartridges). 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. (function() { AVG 28 ft/sec and AVG 16.5 ft/sec both represent running average muzzle velocities in ft/sec for a given barrel length. ALL Bulletin content is copyrighted, 2023 AccurateShooter.com. NOTE: Many shooting newbies may see the number combination 7.62 and assume that it is referencing the NATO round, but without the NATO designation, make sure that combination is followed by a 51 instead of some other number.

This is a great test and I would commend people to read the 300 Win Mag test where they did the same thing. The cartridge case (a.k.a. In experienced hands it can hit a 1,000 yard target. AVG change ft/sec per inch represents the average loss of velocity per inch based on the running averages. performance comparable to the proven .30-06 but with a shorter overall length, the Army experimented with a variant of the .300 Savage that is designated the T65, a good two years before the 7.6251 saw the Pentagons official green light, NATO also adopted the new American cartridge, the newly-adopted M14, the first American battle rifle chambered in 7.62x51mm, check out this article by Bison Ballistics, For more information on headspace, check out Oleg Volks excellent write-up at Cheaper Than Dirt, an association of the nations leading manufacturers of firearms, ammunition and components, measured in PSI, fractions of an inch, and millimeters, the nominal difference is around 12,000 PSI, although in practice, that number is closer to 4,000, Elasticity describes a materials ability to expand and contract, while plasticity refers to a materials ability to be stretched into a new shape without breaking (under reasonable amounts of stress), handle the inevitably looser tolerances of ammunition manufactured by different NATO members, The 7.6251 NATO chamber is imperceptibly longer than the .308 Winchester, extending between 0.006 and 0.010 inches beyond the .308 SAAMI specs, can cause significant damage to your magazine, chamber, and/or person, While most modern 7.6251-chambered firearms are specced to safely handle .308 cartridges, 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. The contents of Rifleshooter.com are produced for informational purposes only and should be performed by competent gunsmiths only. Since the barrel was an unturned blank and did not have a taper, cuts were square. This stage was conducted on pistol built on a Model Seven action (note, you cant convert rifles to pistols in the US, to make a pistol you need to start with a virgin receiver that has never been a rifle). Velocity was about 10 FPS below that of my 30 Border. this insane project much more practical. While the .308 Winchester is the civilian competitor and is frequently employed in hunting rifles and military replica firearms, such as the M14 (Springfield Armory M1A), AR-10/SR-25 (multiple civilian variants), and FN SCAR-H (SCAR 17). 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. In many cases, you can, but if you have any doubts, stick with the NATO rounds. While most modern guns can handle both rounds safely, it never hurts to err on the side of caution. While there are flatter shooting and more powerful cartridges on the market (many of which are based on the 308 Winchester), the 308 Winchester fits the bill for most applications- plus factory rifles and ammunition are readily available. I shook vigorously from head to toe. Drop (Inch) / 0-3.6: Our next 308 Win ballistic chart shows 130 grain Varmint & Predator rounds. Once it reaches 500 yards, it has slowed but it's still maintaining . There are plenty of options from which to choose. 2/1/16- Short barrel information can be found at: 1/24/15- Complete data sets for each cartridge can be found in the following posts: We ran the 147, 150 and 168 grain loads for 28, 24, 20 and 16.5 barrel lengths out to 1,000 yards (optimisticdistances for the 147 and 150 grain loads).

Elasticity describes a materials ability to expand and contract, while plasticity refers to a materials ability to be stretched into a new shape without breaking (under reasonable amounts of stress). Thank you. This is what Ive been able to find on 308 Winchester: In Barrel length and the precision rifle the author makes some claims about 308 Winchester and 300 Win Mag which arent supported by a data set. In the good old days of Precision Shooting magazine (how we miss you! Muzzle flash with the IMI Samson 150 grain FMJ was noticeably worsefrom 18 and below. Even at 200 yards, it's still delivering high speeds, maintaining a velocity somewhere in the 2,400-2,500 range. Never miss a post! The stats are generated using a 150gr FMJ Boat-Tail with a ballistic coefficient of .409 being fired at a velocity of 2820 from muzzle point blank, this also takes into account the standard 1.5" scope height, and a gun that has been sighted in at 100 yards. ATTENTION: Effective Sept 1, 2020, the BBTI Project is in "Archive Status." _gaq.push(['_setDomainName', '.accurateshooter.com']); No guessing, no models, no arbitrary numbers. 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.

Copyright GunData.org 2015 | Koenig Media, LLC | Links | Sitemap | Advertise. It's fine to 600-800 yards and is fine at that range out of an 18" barrel. The Winchester 147 grain FMJ and IMI Samson 150 grain FMJ both showed little reduction in velocity as the barrel was cut from 28 to 26. Yes, I do. When we cut our 6mmBR barrel down from 33 to 28, we only lost about 8 FPS per inch. I think data sets are great. The statistics shown above demonstrate the advanced speed capabilities of the 6mm ARC. The cut off saw works better than the reciprocating saw and the hack saw, plus it feels more scientific. The results from Rifleshooter.coms .308 barrel cut-down test are quite different than the results we recorded some years ago with a barrel chambered for the 6mmBR cartridge. While most modern 7.6251-chambered firearms are specced to safely handle .308 cartridges, older NATO-chambered guns are not. Over the past few years, Rifleshooter.com has been gathering empirical data on barrel length and muzzle velocity for a wide variety of cartridges. Of course, this all takes place within mere fractions of a second. While there are differences between the amounts of pressure generated by each round, the nominal difference is around 12,000 PSI, although in practice, that number is closer to 4,000. (Yes, grains are an actual measurement of weight.). 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. (function() { For more information on headspace, check out Oleg Volks excellent write-up at Cheaper Than Dirt. Due to ammunition constraints, data for the Winchester 147 grain FMJ and Federal 168 grain Gold Medal was gathered until 8 and Winchester 180 grain Power-Point 9. Last week I found out Cerakote has a color called USMC Red. My data showed an average change of 27 ft/sec per inch of barrel. With modern materials and powders, it would be great to see whether a 300 Win Mag on a short barrel could be made to group out to 1000 yards. The Federal shows a fairly straight line. The .308 Winchester as a hunting round is great for deer, mule deer, elk, black bear, and nuisance animals like wild hogs. It includes gauges in .001 increments. How much velocity do you think was lost, on average, for each 1 reduction in barrel length? I think the value of this data is worth the time, effort and expense. 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. The IMI 150 grain FMJ 7.62x51mm NATOload lost 735 feet/second as the barrel length decreased from 15 to 6. Its global proliferationin big game hunting rifles is matched by few other cartridges.

Looking for the perfect accessories to accompany your new .308 or 7.6251 rifle? When we cut our 6mmBR barrel down from 33 to 28, we only lost about 8 FPS per inch. 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. The results from Rifleshooter.coms .308 barrel cut-down test are quite different than the results we recorded some years ago with a barrel chambered for the 6mmBR cartridge. This means that when firing a .308 round in a 7.62 chamber, the .308 brass will stretch beyond its intended elastic range. Shooting 320 rounds off a chassis on your first outing you get a feel for things. Note: I also fired a 30 shots of the IMI Samson 7.62mm 150 grain FMJ with the 28 and 16.5 lengths- Ill discuss why later. It was only a few days after a historic blizzard passed through my state. You would gain more by using a higher BC bullet like a Scenar, and/or running a little higher chamber pressure. No, personally, it seems like a silly idea to me. At 55 grains, its bullet achieves 3,910 fps; at 100 grains, 2,960 fps. 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. Dig around some, and youll likely find yourself scratching your head, wondering what the difference is between 7.62 and .308 rounds.

Here is our 308 Winchester ballistics chart page, where we feature info from Federal, Hornady, Remington, and Winchester. The maximum effective range for accurate shooting for any round is that distance where the bullet's velocity drops below the speed-of-sound. How to Sight in a Scope - Step by Step Guide. A. This resulted in a velocity loss of 94 feet/second. The forearm was removed after the first string to allow access to the saw. Why you ask? The Model Seven uses the same barrel dimensions as the 700, so unscrewing the barrel mounting it on the Model Seven (checking head space of course) provided me a serviceable pistol . The 180 grain .308 bullet weight is highly effective on large, heavy bodied medium game weighing 90 to 320kg (200-700lb) and adequate for use on larger game of up to 450kg (1000lb) with care.
