[QUOTE="The Surgeon, post: 559753, member: 36761"] Shortgrass makes a valid point. Let me take it a bit further, as far as harmonics is concerned. Would it not be possible to have two barrels of equal specs except for the density? For instance, one barrel be a heavy target and the other a typical hunting barrel with matching specs except for density. At that point one could conclude, in theory, how much harmonics plays a role in velocity. I feel safe in saying that with all the members posting and in watching, that some conclusive data would have been revealed. At least in the case of the Lilja test the 338 shows measurable gains up to 30+". It would be hard for me to compare this test and it's results to my 308 win, there are just to many differences in the two rifles. It is possible to conclude that barrel length and velocity could be different for each rifle. I am sure there is data out there that deals with this very question, aside from Lilja. It's just a matter of finding it. Shortgrass, is leakage always present to some degree? One thing is for sure, as this thread goes on the more question arise. I am going to make a few calls to some of the barrel makers and see what info they may have, if any. [/QUOTE]
