.308 barrel lenght?

I am thinking of building a .308 bolt action rifle and am most likely going with a 1/10 twist 26" bull barrel. Weight is not an issue. Can I gain any accuracy or any other benifits if I was to get the barrel in 28" or 30" instead?

1 in 10 is a good twist rate for most bullets over 160 grains.

The barrel size is your call But I would recommend something like a palma contour around 28"

You dont gain much over 28" and the rifle will be muzzle heavy.

I like the Sendero contour or a #8 Lilja contour in 30 cal.

The true "Bull" Barrel is a straight cylinder and serves no purpose in a longer barrel.

Just a recommendation.

Re: .308 barrel lenght?

I have studied this myself because I had a Sendero that shot well but the long barrel wold bang into deer stands and was a little tough to shoot off hand. What the experts seem to say is you gain velocity with the longer barrel and not much else. My 20 inch LTR loses about a hundred feet per second compared to the longer Sendero I sold. What I gained is a rifle that is a little more accurate and a lot easier to handle. The shorter barrels are more rigid and I think that helps in the accuracy department. My Sendero would shoot FGMM 168's great but every other commercial ammo would open up. For example the combined technology bullets would go into 1 1/2 on the Sendero and all three holes are touching on the LTR. In fact the first three commercial ammo tested all grouped with the holes touching! I was wary of letting the Sendero go as it has grouped under 3 inches at 500 yards but only with Federal Premium. Boy was I tickled when I first shot the LTR. I would still like to have a longer barreled 308 for long distance shooting because to get the 100 fps I lost because of barrel length, I have to shoot 150's in the LTR and they will probably not prove to be as accurate. I got some Berger VLD's and a quick load set up to barrel time the test load but have not done so yet. I realllly enjoyed my Sendero but I love my LTR!

In reading my reply, I don't think I really addressed your question. I would think that you would not really gain much velocity or accuracy in going with longer than 26 inches on a 308.
