I have a Douglas #3 barrel ordered, chambered for 280 AI. I had the 'smith order it at 26", thinking if I didn't need it, I could always have him cut and recrown it at 24" or whatever length I wanted.
The question I have is will I see any advantage to having a 26" barrel over a 24" or 25" or XX? At what point does the length become counterproductive?
Thanks for your input!

In my experience, the difference between 22 inches and 26 inches averages out to about 25 to 30 fps per inch of barrel in cartridges based on the '06 case. This has held true for both factory and AI cartridges. The exception has been one .25-06 that I cut from 26 to 24 inches--the velocity loss in that one was a little over 100 fps with most loads in the 2 inch shorter barrel. FWIW, my .280 AIs have 23 and 24 inch barrels and both shoot within a few fps with the same loads...

My 280AI wears a 22 inch barrel, velocity loss over a 24 is nominal at best.

No doubt I'd go and stay with 23".
Now if it was a lefty action then I'd go with a 33" tube as I'd be for needing all the help I could get...gack gack gack

My .280AI wears a 23 inch #3 Shilen and its just about right. Very little loss in fps to the longer snouts.

Thanks for all the input, guys. I weigh enough, without carrying around an extra coupla inches of barrel if I don't need to!

I did the same thing with a Kreiger barrel for a 280AI finally settled on a 25" rifle balanced pretty good with that length. I'm lucky that I live pretty close to the gunsmith and he cut it at 26" called tried the rifle then had another 1" taken off. I don't consider 1" extra barrel lenght a problem as I'm more concerned with how the rifle come up to my shoulder. I was up gunmsith shop last week and my new 270WSM will either have a 25" or 24" barrel first cut will be at 25". When I get into the heavy contour barrels like #4 mag I'll normal have wind up with a 24" barrel #3 is pretty light weight. Well good luck

Had a couple of 280AI. Like most 23" Seem to be the best of both worlds.

got 3206 from a 24 3/4" #5. Rifle handled great. And not a burden to carry either.

Anything less than 24" just seems like waistin' its potential. But what do I know??

OCC-my tests with cals very close to it, show that per inch taken or added the fps change will be between 25-33 fps. So if one goes from 24 down to 22, we're talking a total max change potential of 66 fps and most likely less.
I don't know about others but I'll gladly give up some barrel life and not wotty one bit.
4 me choosing the length of a tube is more about what size hole is in it, what kind of a stock is it going in and what contour of a tube is being used.
I've found that kind of thinking to be a good way to go about business as opposed to worringing about a few fps.
But, that is just me and my ways and they sure don't need be adopted by others cause I could well be wrong.

I like 23" myself, plenty of speed yet handy to manuver.

So, I just need to have it cut at 20", then have a pocket full of 1" extensions to screw on as needed?
