    .308 - 1 in 10" twist or 1 in 12" twist?

    Hi All,

    Looking att moving up a bit from my .223 to a .308 and just checking out some options to start with. Primarilly looking at either a Rem 700 SPS Tactical which has a 1:12" twist or a Rem 700 Tactical AAC-SD which has a 1:10" twist. Just wondering if either has a specific advantage over the other. (I know the 1:10" should allow me to use heavier bullets, but is there any real advantage to that in .308?)

    Also, if I go with 1:10" the Rem 700 Blackhawk Axiom II also has a 1:10". Are those stacks any good at all? I was thinking I could swap it onto my .223 and put the HS Precision I have on the .308. But, if the Axiom II is Junk I'd stick with the AAC-SD and spring for a new stock. Don't want to "wreck" my .223.

    Thanks in advance for your feedback.

    I also bow to the wisdom of avolcek on the Axiom. In fact if you want I'll mail you mine! I bought a used Howa and it came with that stock. I gave it a test run and even though I have read everywhere that the Howa is a MOA or better rifle I couldn't do better then 2-3 MOA. Even the guys I shoot with (far better marksmen then I) could do no better then 1.5 MOA. I picked up a B&C stock and with no bedding or any other work put it on and it now I have a .75 MOA gun. So, skip the axiom its not that cool looking anyway.

    Go with the 1:10 twist barrel. The 1:12 will stabilize up to 175gr matchkings, but the 1:10 without a doubt will let you stabilize the heavier bullets better. Usually, the heavier the bullet, the higher the BC, and the father it will shoot accurate. There are a few exceptions to this rule (like the 155 scenars). Also, The AAC is threaded should you decided to purchase a suppressor in the future.

    This is a fairly regular discussion point.

    The answer really depends on what sort of shooting you will be doing?

    If you go 1:10 then you limit yourself to heavier projectiles.

    With a .308 there isn't much to be gained from going over 175-180 grs. The 175 gr SMK is pretty ideal for shooting from a 1:12 twist.

    If you go 1:12, then you will also have the option of using 155gr pills, and there are some really good commercial loads and projectiles out there.

    I wouldn't go a 20 inch barrel unless you are planning on limiting your range as you will lose a bit of velocity.

    Hope this helps.

    As I understand it... The AAC model mainly has a 1:10 twist to better deal with heavier subsonic loads with a suppressor.

    I would probably opt for a 1 in 10" all things being equal. You would be able to shoot all the .30 caliber bullets from 110gr to 220gr. That being said, I don't think you will really notice much of a difference either way. I would pick the rifle you like best. The difference between a 1 in 10" and 1 in 12 " rate of twist wouldn't be a deal maker or breaker for me in that instance.

    I hear this comment from time to time but there is something I don't understand. If a 1:10 is a better twist rate, why isn't it standard on most .308's?

    I would go with the 1:10 twist also, just yields alot more bullet choices if you reload.

    Does anybody know what standard ammo for .308 rifles with a 1 in 12" twist is used by LE? I am mainly interested in the bullet weight. Thanks
