Has there been any test to determine barrel length for maximum velosity?
OK, I will quote dragman. He said, ". . . anything more (than 27-29) you will start to lose velocity . . ." So, you guys stick by that statement??

Hmmm. Anecdotal at best.
Let's look at readily available test results from a reliable source. Velocity vs. Barrel length with the plain old 30-06, conducted by Springfield Armory:
24" - 2709 fps
28" - 2776
30" - 2833
32" - 2848
They stopped at a 32" barrel because that was the longest they had available.
So, are you telling me that if you cut 3" off of your 30" barrel you'll gain velocity? I don't think so.

I think that is about right. a 29" will have more muzzle velocity than the 30. I personally have a 6.5X284 with a 30" barrel and my friends with a 27" barrel with the same load has me by 35FPS.
and as you pointed out that is apples to oranges.....you dont have his bbl, he does not have yours....so it is not valid.
now take your bbl and cut it off to 27....that is if you truely believe what you posted. you will have less weight and will have gained velocity...put your money where your mouth is....
ps i ran numbers in quickload..and you GAIN velocity in 6.5x47 from 27 to 30 inches.....

You don't really believe you'll lose velocity do you?
