Does barrel length matter for 308?
Our experience has shown that for a . 308 caliber tactical rifle with the overall rifle weight and shooting distances mentioned earlier, a barrel of 24-27″ is optimum in one of the fairly heavy contours we discussed. Closer ranges or other considerations might dictate a shorter barrel.
Does the length of the barrel affect distance?
The length of the barrel does affect the velocity of a projectile and therefore will affect the accurate distance and the total expected and real distance of the projectile. A general rule of thumb is the longer the barrel, the higher the velocity.
Does the length of a barrel affect accuracy?
A longer rifle barrel is not more accurate. The sight radius is longer (with iron sights and not a scope) which is better for the shooter to get a more accurate aim. Increased accuracy in a longer rifle barrel is a myth. There are many factors that affect accuracy in a rifle but barrel length is not one.
Why does a 308 have a shorter barrel?
This is because the pressure behind the bullet even at 32″ is still many thousands of PSI (like 6,000-10,000) and it only takes a couple thousand PSI to move the bullet in the bore. I shoot a 30″ barreled 308 win and even with really mild factory ammo, I get much higher velocities than 20-24″ barrels do.
Are fluted barrels less accurate?
Practical Takeaway. By all accounts, fluting a barrel has little effect accuracy, either positive or negative. If done properly by a skilled gunsmith, fluting may lighten your rifle a bit, and it may have a subtle impact on the rifle’s accuracy, possibly a positive one.
Why are 308 barrels shorter?
Why do 308 have shorter barrels?
Why does a longer barrel increase range?
Given that the force of the propellant has not been expended, and longer barrel imparts a greater energy and hence a greater velocity and range. The length of the barrel does affect the velocity of a projectile and therefore will affect the accurate distance and the total expected and real distance of the projectile.
Is an 18 inch barrel good for hunting?
Lots of trigger time for just one rifle and it worked just fine. I wouldn’t hesitate to hunt with a 18″ 7-08. All you are giving up is some fps. Often the shorter barrels can be more accurate than the longer ones as a barrel at 18″ is much stiffer than the same contour barrel at 22-24″.
Can you cut a rifle barrel in Canada?
Get caught with one at the wrong place and time, and you’re looking at serious time in a federal penitentiary. But if a shotgun comes from the factory with a shortened barrel, even as short as 8½ inches, you’re in the clear – they are completely legal in Canada with no special restrictions.
What is the barrel length of a 308 Winchester rifle?
308 Winchester / 7.62x51mm NATO: Barrel Length versus Velocity (28″ to 16.5″) Introduction. Released by Winchester in 1952 (and adopted by NATO in 1954 as the 7.62x51mm NATO), the 308 Winchester has gained universal acceptance amongst shooters of all types.
Why a 30 inch barrel on a 308?
Palma shooters often use 30″ barrels to allow them to push the 155’s to 3000+ more easily. For shorter ranges, out to 600 yards or so, the shorter barrels shoot accurately and the velocity loss is less important. In a hunting application, the .308 isn’t going to take you much further than that, so you can get away with a shorter barrel.
How much does the velocity change when you reload a 308?
For instance, 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”. My data showed an average change of 27 ft/sec per inch of barrel.
Is a 308 a good rifle for hunting?
For shorter ranges, out to 600 yards or so, the shorter barrels shoot accurately and the velocity loss is less important. In a hunting application, the .308 isn’t going to take you much further than that, so you can get away with a shorter barrel.
