308 Winchester / 7.62x51mm NATO: Barrel Length versus Velocity (28″ to 16.5″) Introduction. I'm just pointing out that if you had to engage at distances beyond those normally encountered this ammo would perform out to 400m. When you take the 16” barrel and fire at that range, you’re looking at 4.1 mils of drop, which is The Savage Axis II XP is just such a gun though. And sure, there are some cheaper .308 single shots out there, but the price difference isn’t much, and you get a lot more bang for your buck with the Henry. The 308 is more forgiving in velocity from a short barrel it isn't going to lose as much, but the 6.5 will make better use of the velocity . Today, the modern .308 AR style rifle isn’t properly an AR-10 as originally designed, but is a scaled up AR-15, and generally uses some common parts like the trigger group, pistol grip, buffer tube assembly and stocks. Diameters that are bigger mean greater stiffness but the extra weight isn’t always desirable. Note the generous recoil pad. However, the 22” barrel Henry single shot has a lot more for us. It then begins a straight taper to .900″ at 29″, a taper of .0146″ per inch. This is going to be another highly contentious section, and for good reason. I strongly prefer a 1-10" twist if heavier bullets will be used, however my 26" target rifle has 1-11" twist and stabilizes 190 grain Berger VLDs to 1,000 yards or more. I ran some numbers through a computer program I developed that calculates barrel weights and stiffness values. Today, the .308 Winchester (and 7.62 NATO) are if not the most popular rifle round in the world, one of the most popular rifle rounds. A threaded barrel fits common muzzle brakes or even suppressors. Anyone know the effective range of 220gr Sub-Sonic 300 Blackout rounds from a 16" barrel with 1:7 twist rate. The SCAR17 is a phenominal asset, bar affordability. The effective range of an M60 is 1200 yards with a 22" barrel. Extensive built in safety features ensure this gun can only be fired when the barrel is locked into place, the hammer cocked, and the trigger pulled. So much so that it is tough to pin down the best 308 rifles. Second. The  Howa KRG Bravo is a superior quality .308 bolt action rifle that is more than capable of being used as a sniper rifle, but won’t break the bank. In this case, the Tikka T3X TAC A1 is clearly meant to be sold and used as a tactical rifle. Think 20" or longer. Henry Repeating Arms has mastered the traditional rifle market, and embraced the nostalgia and mythology that is part of our national heritage. It was used in the War in Afghanistan and the Iraq War. However, there are a few things that are generally considered must have features on a .308. To make a recommendation for a .308 caliber barrel to be installed on a Remington 700 action, there are a couple of questions that need to be addressed. The effective range of a M14 is "800m+" with optics and a 22" barrel. Simply add the optic of your choice to it, and it is ready to go. Save my name, email, and website in this browser for the next time I comment. Therefore, we can see the ideal .308 rifle will have a sufficiently long (and well made) barrel to develop accuracy and the full potential of the round, as well as a comfortable stock, suitable trigger, and either well made iron sights or a quality optic. For long range I have a Win. The adjustable match grade trigger allows for superior accuracy when paired with the precision enhancing 24” barrel. Quality of these builds range from top quality to questionable. It comes equipped with a Law Tactical GEN3 Folder. Think 20" or longer. The cover of the January, 2000 issue of Tactical Shooter shows one of Robar’s SR-60 rifles. There are a lot of reasons to own a single shot .308. Howard on May 18, 2015 at 2:18 pm There are conflicting articles regarding 308 barrel length and velocity. I have a 16 1/2 inch Ruger 77 Compact in .308 which I consider the Ideal patrol rifle for many situations. Featuring an 18” barrel, synthetic G3 style furniture, top receiver Picatinny rail, and another mounted on the bottom of the handguard. While there is no standard format for .308 AR style rifles, two competing standards have evolved. With that in mind, we were after guns that offered a bit more than others. The chamber is of standard SAAMI specification in .308 Winchester and the barrel features a 1:10 right hand twist. Advertised as one of the lightest .308 AR style rifles, the GII is an ideal carbine for somebody who wants more punch than is delivered in a 5.56 carbine. For hunting, the M&P10 offers an ideal balance of usability and power. Also, too much barrel weight on a lighter-weight repeater action, like our preselected Remington 700, can affect the bedding and create problems that wouldn’t exist with a shorter barrel. For those who want the most power in a short barrel weapon for maximum maneuverability, and don't mind wasting some energy to get it, the short barrel .308s will kick ass. I was wondering if anyone knows the effective (ability to knock down a BG)range of a 16" bbl .308 rifle? However, some excellent (and timely) work by Bill Marr at Rifleshooter.com showed a steady drop in 224 Valkyrie velocity all the way down to 16.5". Two years later, the 7.62 NATO was born from the same research and experimentation. 2. The butt features an adjustable comb, while the rifle itself sports a 24” match quality barrel and accepts common removable AICS pattern magazines.

These are useful all-around barrel lengths for such cartridges. This is a highly subjective category. The first question is overall rifle weight. Because it fits a standard AR buffer tube, you can readily swap out the stock for something else if you are so inclined. The market for .308/7.62 rifles ranges from affordable blue collar truck guns, to high end precision bolt action sniper and match target rifles. So, if we’re going to settle on the 168 grain Sierra Match King or another bullet of a similar weight and style, then a 12″ twist rate is the best choice. Like actual married life there are always trade-offs. A 20" tactical .308 for police use will usually be shooting 168gr Fed Match ammunition and the practical range on that is about 800yds. Of course the first question one might ask is “what is a tactical rifle?”. 1. Personal taste, tradition, local culture, end use, budget, and so much more all must be considered when choosing a rifle. Suggested loads: .308 Winchester Barrel length: 22” No ID Sectional Density Ballistic Coefficient Observed MV fps ME Ft-lb’s 1 FL Hornady 150gr SST.226.415 2750 2518 2 FL Hornady 150gr SST SF.226.415 3000 2997 3 FL If it is desirable to make the rifle a little heavier, then I would suggest using one of the straight taper barrels, like the NBRSA Heavy Varmint classification or a close variation. Closer ranges or other considerations might dictate a shorter barrel. The barrel on this one is button rifled, and since it’s chambered in .308 Winchester, it features a 1:10 twist rate, or one full bullet rotation in 10 inches of barrel length. What kinda range would that lil rig be good for? 21” 2774 2501 ... that a 20” barrel for instance is a better all around length for both CQB and long range. With that in mind, tactical is as much a mindset as it is a type of rifle. What it lacks in fancy features, it makes up for in Colt quality manufacturing and reliability. Every aspect of it has been designed around highly accurate, long range shooting. Built to serve a price point first- no frills or premium components beyond the trigger here. There are no adjustments or modifications that can be made to extend this range because the range is determined by the bullet,” John Lott, president of the Crime Prevention Research Center and author of “ More Guns, Less Crime ,” told The Daily Caller News Foundation in an …
