Saiga AK .308 21.5"

Just bought a Saiga .308 on gunbroker with a Dinzag Arsenal 2-stage trigger and a Black Poly AK stock. I plan on an ATI Tactical Grip, Muzzel Break and Aluminum Quadrail. I mostly see the 16" but I think the 308 round really needs 18+ to fully stabilize. Anyone have experience with shooting one of these with the 21.5" barrel?

What is the rate of twist? I believe both Savage and Remington use a 1 in 10" for their 20" barrel .308 Win.
 
I've got a bone stock one. It shoots fairly tight with 150 federal powershok, but occasionally I throw a shot. I'm going to convert it with an adjustable trigger. I share your thoughts on barrel length, although the 16" would make a great hog/brush gun.

stabilize

HOw long a barrel is has little if anything to do with how "stable" the bullet is when it exits same. Alll a bullet knows is the rate of twist applied by the rifling, and the veloctiy, usually a component of barrel length.

But a slug from a 14.5 tube is no less "stable" than one from something longer, given the same twist rate and projectile type, and velocity.

So you’re saying a .38 Special from a snub nose revolver is every bit as accurate as the same .38 special out of a 16” lever action carbine?

I’m not trying to be a smart alick, I guess I don’t know what you mean?

not to get too far off topic but

in theory the spin is imparted on a bullet to achieve stability in done in the first inch or two of a barrel. Otherwise bullets fired from a snub nose would consistently keyhole. Longer barrel length allows for increased velocity and helps the shooter with the sight radius
 
The biggest increase in accuracy from a 4" barrel to a 16" barrel is due to the longer sight radius. that's roughly 4 times longer for the carbine than the revolver.

The difference in sight radius is much smaller for a .308 saiga, and the difference in group size would be much smaller.

Actually it would be. The problem isnt the barrel length in the 2 vs 16 inch barrels, its with the shooter.

The longer sight radius the easier something is to shoot.

It doesn't take much movement to maginfy the error. Here is an example. To determine the sight movement to move the sights 1 moa, divide the sight radius by the distance (in inches).

Take your 2 vs 16 inch as an example. At 100 yards or 3600 inches, divide 2/3600 and you get = 0.00055

16 inches / 3600 is .00444

That's why its harder to shoot distance with short barrels.

But the gun nor ammo causes that movement, the shooter does. Both would stabalize the bullet.
