What is a good barrel twist for a 308?

308 Win. is most commonly barreled with a 1:12 twist. This is probably because use of long, heavy bullets was not envisioned in shorter actions. However, in . 30 caliber, even a 1:12 twist is versatile and can usually stabilize 190-grain match bullets and 200-grain hunting bullets.

What is the best bullet weight for a 308?

The 110 and 125 grain bullets make the . 308 a useful round for varmints. Velocities at the muzzle can exceed 3,200 fps, providing devastating performance on pests or predators.

Why do 308 have shorter barrels?

Velocity loss is relative, the case capacity and powder means that a longer barrel doesn’t add as much speed as with a 300 wm with more slower powder to burn. 308 win uses faster powder and less of it, so a longer barrel does less.

How accurate is a 308 with a 20 inch barrel?

I experienced a 20 inch barrel is more consistently accurate because of the harmonic impact. Thousand yards with a 308 is a real feat. It’s really not designed for such, more like 800. I had a dear friend who has since passed, that was a Palma shooter since the 60’s.

Is a 20 inch barrel better than a 24 inch barrel?

In my opinion, a 20″ vs 24″ barrel, the most you’re gonna notice is the weight because the difference in isn’t significant. There are PLENTY of 20″ barrels that are not ‘bull barrels’ which are 1/2 MOA accurate but if you’re wanting a semi-auto rifle with that kind of accuracy for $1300, that may very well be a stretch.

What is the best bullet for a 308 Winchester?

The 168 grain Sierra Match King is an excellent bullet in the 308 Winchester, and is probably my first choice for the shooting situation we’re discussing in this article. This bullet has a ballistic coeficient of .475 and with a barrel of 26″ or so, a velocity of 2800 fps is reasonable.

What is the best barrel length for accuracy?

So from what I’ve heard a bull barrel is the way to go for accuracy. I’ve heard 20″ is good enough especially if its bull barrel, bc there is enough powder burn so you get enough velocity and such at 1000 to stop someone easy.
