I'm having a .308 built on a Remington action for hunting and would like to use bullets in the 150gr-180gr weight range, most likely 150gr, 155gr and 168gr. Which barrel twist do you think would be best for the job 1-11'' or 1-12''
I have no interest in bullets over 180gr.
Thanks

The faster twist for the 168`s (1-11).
The slower twists for the 155`s(1-12 and 1-13).
Remington sells there factory model with a 1-12.
I think you would be good with a 1-11 and 1-12 for the 168 grainer.

I like 1in10 for my 308 caliber rifles.

I like 1:10 but dont usually shoot lighter than 165gr.
Keep in mind a heavy lead flat based bullet will shoot well in a slower twist than the same weight in copper because of the length. If you get to pick the barrel, why not build it to shoot the exact bullet you like to use the most?

I think the 1-13 does not shoot the 155`s as well as the 168`s out to 200yds-at least that is what i can recall from a while back.

Unless the 155 is shorter than the 168, this seems to be back to front.

308 factory rifles were initially provided with 1/12. Now they vary between manufacturers from 1/12 to 1/10. Sako/Tikka use I/11 in 308, 30-06, and 300. This may be a manufacturing expedient, but I am inclined to think that the reasons below also drive this move by manufacturers to faster twists in 308.

When the 308 was introduced, most projectiles had lead tips and flat bases. Now we have plastic tips, boat tails etc on many excellent hunting projectiles. These are much longer projectiles for their weight and have a different balance point, meaning that a faster twist than 1/12 may be desirable.

I would suggest 1/11. This will let you use long, tipped 165s, and will be absolutely no problem with lead tipped flat base 150s. If you should desire to load 125 Ballistic tips, these will also shoot just fine in 1/11.

Shootaway, you've got it just backwards. A faster twist is needed for a heavier, longer bullet, although most 1 in 12 twist factory barrels shoot 168s just fine. If you're having your rifle re-barreled ask your gunsmith.

your right-sorry about that!

I would be much more interested in knowing more about better designed actions first.

Look at Mausers, old M70's, some FN's etc before spending time and money on that entry level push feed action.

Look for a rifle with CRF, a M70 type three position safety that controls the firing pin and more.

The twist is not all that critical. A one in 10, 11 or 12 would be fine

I have a 1 in 10 twist in my 77 International and it loves those stubby 150 Speer mag-tips. Seems to buck conventional wisdom.

I would use a 10 twist. It will shoot the greatest variety of bullets with accuracy. Why put a limit on the bullet type, weight, or shape you can shoot?

I have a 1 in 12 that works just fine. Going faster than you need apparently costs you some velocoty, although I think that is negligible and will also apparently foul more. The reply that you can choose around your preferred bullet is correct. There are resources online that allow you to determine stability for a bullet at a velocity with a specific twist. For really high bc heavyweights a 1 in 10 is required. If you are unsure as to your plans a 1 in 10 covers the bases.

I only shoot .308Win for work or competition. My work rifles are 1-11" and shoot 175gr SMK with good precision and stablility. In a Palma gun I think anything from 1-11 to 1-14 is fine depending on if you choose to shoot 155gr only or if you intend to use it with 175gr for other stuff.

My Brux barrel is 1:11.25 and it works very well. But I don't use anything heavier than 168 grain bullets in it. The rest are 1:10 for 30-06 and 1:12 for 308.

Dear God now we need CRF for a .308.......

That entry level push feed action is stronger and much more easily accurized than any you mentioned......

Dangerous game rifle...sure CRF is justified......small caliber centerfire cartrige...especially one noted for superior accuracy....why CRF?????

I couldn't agree more, far too many put emphasis on CRF, I wouldn't give you two cents for one. I've been using push feed all my life and never felt particularly disadvantaged, and that includes up to .338 WM and .340 Wby.

Thanks for all the replies guys,I'm going to go with a 1in11 twist.

Unrelated to your question of twist.

I don't know how important weight is to you, but too many gunsmiths tend to use an unnecessarily heavy profile barrel.

This can result in your pet project ending up being disappointingly, and unexpectedly heavy. Being in the UK, I expect that you may use a moderator and this will also affect weight and balance.

Having some input in the barrel selection process and not blindly accepting the builder's offering can avoid this. A quality barrel does not need truck axle dimension to provide well under MOA accuracy for 3 shot groups.

Enjoy the project and using the results.
