Is a longer barrel better, i.e. 24" vs 30"

While I am waiting for that stupid new years ball to drop so the girlfriend and family will settle down and go to bed... I continue my shopping/planning for my 22-250 custom rifle. I plan on using a Douglas barrel, and I am really looking at the #9 profile, straight taper and 30" long!.
SO the question is... WILL a 30" barrel give me more accuracy, and velocity than a 24 or 26" tube? Is it significant at really long ranges... 500 yards?

I love doing stuff like this online. So far tonight's shoppping spree has yielded...
Mauser 98 complete action.
Boyd's varminter gunstock
Douglas barrel
Mauser double trigger
BSA Catseye scope
Moly bullet coating kit (Thanks Santa C)
Hornady Dies for 22-250

I need scope rings and buttpad I think
I have a source for brass and many sources for bullets.
Anything else I missed?

Well got to go, it's almost midnight, happy new years woohoo, yippee and all that.

Thanks all

30" #9 barrel would be great on a custom action such as a Nesika bay or Farley, but on a Rem, Win, Ruger or Mauser 26" or 27" is all i use.
a 30" #9 barrel weighs what 10lb or so?

I second Gonehunting's statement. 26" is plenty for a 22-250.

26" is perfect for a 22-250

A longer barrel will achieve more velocity to a point, then you have diminished returns. There won't be any accuracy advantage. Short and stiff is for accuracy. Longe range accuracy [aka 1000yds] is a compromise of slightly less accuracy to gain velocity. It works well and I shoot 30" barrels with a HV contour in my F-class guns. spock

I would suspect that the differnce in muzzle velocity between 30 & 26 inches is going to be about 150 fps max. Once u reach 400 yds or so that will not mean much and certainly won't mean anything past 600 yds. At 600 yds you will be under 100 fps difference in velocity.

At 900 and 1000yds which we generally shoot, the extra barrel length is free velocity with a medium size cartridge like .260Rem/.308Win. 30" works for us.

One can always use a 26" and a bigger case to drive the bullet harder, but why burn up barrels faster. Each to his own. spock

I would sugest a barrel bedding block for a 30" barrel on a mauser action, they are not a very stiff action, the other alternative is to bed the stock for 3-4" in front of the action. You didn't say what twist or bullet you were planning on shooting, the biggest "gain" with the 30" barrel would be with 70gr or bigger bullets.
