I'm in the school of thought that simply says "you gotta hit it first." A .300 Winchester is really about the max a 30 caliber will handle effieciently, and when you compair it to the .308 Norma Mag you see very little difference between the two, or better yet compair the .300 to a .300 Weatherby in 180 grain class rounds. Untill you move up to the 200+ grain bullets; there's not all that much difference. Personally I like the Norma better than the Winchester due to the longer neck, and bullet performance with heavy bullets shows up between the two case designs.
When you opt for a shorter barrel it does change the equation quite a bit. You use different powders that tend to burn slightly faster. But on the otherhand have you ever thought about how much powder your just blowing down the barrel unburnt? Or the opposite in the idea that you burnt all the powder in the case before the bullet left the barrel? If you get similar velocity out of a 24" barrel as you did with a 26" barrel; your then left with a 26" tuning fork. But if you need the whole barrel length, then it's another story. I doubt you will see a 100 fps loss with the right kind of powder, but will rid yourself of a lot of bad harmonics going thru the barrel
