.308 rebarrel choices

Hi All!
I'm looking to rebarrel a mid-70's model 700 in .308 and would like some input.
What I'd like to know is what is the best twist rate for the .308? I know that the faster twists stabilize the larger bullets, but does that adversly affect the smaller bullets? I'd like to be able to play with the full range of bullet weights.
I'd also like to play with long range (800-1000 yards) but not necessarily to the point of being the focus of this rifle.
Also, what contour/length would be best for a mountain hunting rifle?
Has anyone had any experience with the 5R rifling? Is there any advantage to it (I see Lilja offers a 3 groove- same question)?
Thanks for the help, guys, I really appreciate it!

Re: .308 rebarrel choices

I have been told to buy Rock Creek barrels by a VERY reliable gunsmith. He has shot every brand available over the years, and he says a 5R Rock Creek barrel is where it's at. The Rock Creek 5R .308 barrels are 11.25" twist.

For my .280AI built will be a 100% trued balanced & blueprinted 700 action, trued raceway, squared bolt, with a Jard 14oz trigger, and a stainless 5R Rock Creek barrel. It should be pretty nasty.

Re: .308 rebarrel choices

I would opt for a 1 in 10 unless you have a specific bullet in mind. I run 1 in 8 for heavy subsonic loads,1 in 10 for general purpose and 1 in 12 for the 155 bullets. I have shot light weights threw my 1 in 8 without a problem but have on occasion cursed my 1 in 12 for not running the heavies well. I think one in 10 is a the best bet unless you now what you want to run. I do not know the limits of the 1 in 11 in a 308 win but my 300wsm is a 1 in 11 and it is not fast enough for some of the pills I would like to use.

Re: .308 rebarrel choices

I only shoot 165-168gr for my .308, so 11.25" is perfect for my setup, which is also what my Remington 700 5R .308's stock barrel is. It loves the 168's.

I do have a big box of Nosler Custom Comp 175gr bullets that I have been curious how they shoot out of my gun. Might load up about 20 or so to take to the range.

Have you tried any heavier? Just curious.

Re: .308 rebarrel choices

Alright just got back from the range and shot my custom loads for my .257 Wby Mag, and my .308.

Since i have only tested with 168gr projectiles for my .308 so far, and I have a box of 250 pack of 175gr Nosler Custom Comp .30 bullets laying around, figured i'd test out some... Apparantly my 5R loves the 175's as much as the 168 Custom Comps. At 100 yards I am only 1 Mil lower with the 175's and my side-to-side is dead on for both! So, needless to say, I didn't touch the scope, I just shot with the Mil setup.

So, good to know that now. Tonight I might load up 100 of my new Lapua brass with my 175gr load I concocted to see how well the gun likes both at long distance.

Re: .308 rebarrel choices

I shoot a Rem 700 with a 1/10 twist. It shoots 168 bergers just fine but it really shines with 175's. Also the heavier bullets let me reach out there better and more accurately. It's a good 700 to 800 yard rifle I havent tried 1000 yards yet(still working up my load).
