I'm looking to get my first bolt action rifle soon... I'm thinking of getting a .308 but I'm not sure what twist rate is ideal for common factory rounds.

For my AR I buy a lot of 55 grain 5.56 rounds, because its available and cheaper, and my rifle is also a 1:9 twist...

What is common for .308, and whats the best twist rate to stabilize it? One of the bolt guns I am looking at is 1:11, another is 1:12

I would venture to say that the vast majority of factory made .308 rifles have a 1:11 or 1:12 twist. Both are plenty for the most common .308 projectiles. Special twists ( like 1:13 or 1:10) are for the short/light bullets or the long/heavy bullets.

My .308 has a 1:12 twist barrel and shoots 175 SMKs, 168 SMKs, and 155 SMK Palmas just fine.

One of the reasons I am asking is I have a decent stash of American Eagle .308 Win 150 Grain rounds I bought on sale... and no .308 rifle =) This stuff seems to be a pretty common bullet weight, and I like cheap ammo. I plink more that I target shoot, so often times factory ammo is accurate enough.

The rifle I am leaning towards has a 1:11 twist rate, and I'm not sure if that's too fast of a twist for a 150gr round...

My .308 is a 1:12, and it shoots all sorts of bullets A-OK. 1:11 is also just fine. If you know that you are only going to shoot one type of round then i would pick the twist rate that works better with that particular round.

Remmy 5R & be done with it. Shoots 155's-175's straight as can be.

I plan on saving all my brass from this batch of .308 I have, chances are ill start reloading and playing with bullet weights then, but I still have a long way to go and a lot of learning before I get to that stage.

I purposely didn't mention what rifle I was thinking of purchasing on this thread because I didn't want it turning into a "best rifle thread" and derailing from the topic. But... The Remmy 700 5R is pretty amazing, I saw one with the HS precision stock, stainless, 5R, and amazing rifle, but I didn't want to spend that much not to mention the glass id throw on top would be at least the cost of the rifle itself. I already have a target rifle, and wanted more of a light weight hunting style setup.


I pretty much decided on a Tikka T3 Lite in .308, which has a 1:11 twist. I already have a 3-9x40 scope I plan on throwing on top. Its more of a budget setup for myself, but its my first .308 and my first bolt gun. + Ive always wanted a Tikka.

I recently put in a order for a custom barrel for my Savage .308 and I got 1-10 twist since I will be mainly shooting factory grade ammo. Thats what the stock twist ratio was on the rifle anyways.

how is the Savage compared to Rem 700?... I've read it's a good alternative.

Sorry OP, not trying to derail your thread :o
