Is an 18 inch barrel accuracy?
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″. I am glad to give up 100-150 fps in favor or handiness to carry and maneuver in the woods.
What is the best barrel length 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.
What’s the effective range of an AR-15 with a 16 inch barrel?
That said, the 16″ AR-15 barrels offer a good compromise between the full 20″ length and the short barreled rifle class. It’s still capable of hitting any target the 20″ can hit while only losing about 50 meters of effective range compared to the longer rifle.
Does a longer rifle barrel increase accuracy?
As long as you know your velocity—and your bullet’s ballistic coefficient—you can know your trajectory. Longer barrels are not more accurate. If anything, it’s quite the opposite. Shorter, stiffer barrels tend to vibrate more consistently and are probably more accurate on average.
How far can an AR 10 shoot?
Effective range: Without a powerful scope attached, the AR10’s effective range is about 600 yards, whereas, for the AR15, it’s between 525 and 600 yards. However, with a good scope, the range can increase to around 1000 yards for the AR10, and to around 800 yards for the AR15.
Is there a big difference between a 16 inch and 18 inch barrel?
Its a pretty nominal trade-off in both directions. 16″ is a little bit handier but its easy to over-state that – similar the 18″ little more velocity. One other factor you won’t see mentioned as often – so maybe I’m just more sensitive to it – is that all else equal the 18″ will also have less muzzle blast.
What is the average FPS for a 16 inch barrel?
At 15.5″ (or 16″)you should be shooting around 2500 fps , meaning an average of 100 fps per inch from the 12″ mark. After that point you will generally only gain about 40-30 fps per inch tapering off gradually as the barrel gets longer.
What is the maximum distance a 16 inch barrel can hold?
The 16″ barrel should hold most match grade ammo at supersonic velocity up to 500-600 yards. Supersonic speeds can be guesstimated at about 100 yards per inch of barrel after. Keeping your bullet supersonic beyond 1,000 yards with a 24″ barrel
