    1:10" is the "new" standard twist rate for that caliber. There were 1:12" also, but I think just about everything is 1:10" for the 30-06 except in custom barrels.

    What bullet weight/length were to planning to shoot?

    My 1 in 10 308 shoots 125gr to 180gr well... It seems to shot 125's and 150's a bit better than the 180's. It may just be the fact that I'm a recoil woosie and flinch with the 180's.

    1-10 twist is pretty much standard anymore, it works with the widest range of 30 cal bullets. you should be fine with 165's. If your loading your own then just find the powder that works the best in your rifle :thumbup:

    I use that in my 300 mag it works great, never tried it in my 06 but that is a great powder. I use varget in the 308 and 06. You can also lengthen your OAL to make the groups better, just make sure that they fit in the mag and that you crimp them good

    I'm sure it will work fine for you... I just save it for my 300 mag, cause it uses alot of it

    I use 4350 in my 30-06 loading. I have a custom load with 180Gr Partitions for hunting. It's not a benchrest group, but it's all my shoulder would handle when I was testing loads. :)

    Generally speaking (very generally) for a 30 caliber rifle, a 1-10 twist is generally used for heavier bullets (180-190-200), and the 1-12 is for lighter bullets(125-175). Although you can use heavier bullets or lighter bullets in either one, performance will not be as good as you might hope.

    Additionally, the 1-10 twist rate will foul a little more quickly than the 1-12, but for a hunting rifle, it is unlikely that you will shoot it enough for that to matter.

    Earlier postings were correct about the 1-10 twist being the new "standard" for alot of the 30-06 rifles. Mostly because the 30-06 shooters are heading toward the 180 grain bullet weights, and this twist rate performs well with that twist rate.

    My most recent barrel from Obermeyer for a 300 Win Mag has a 1-11 twist, and it shoots 190 grain SMK bullets better than I can hold...(1.3 to 1.4 inches at 300 yards).

    If you are considering a 30-06 hunting rifle with the 1-10 twist, it will work just fine.
