[QUOTE="scott2345, post: 1228279, member: 97468"] So a shorter, heavy barrel is less impacted by harmonic forces. And folks use those types of barrels for accurate shooting. That seems to say that harmonic forces on the barrel are a bad thing. And if it is bad it seems to be something you would want to control/reduce (shorter/heavier barrel) instead of accommodating (long/thin/free floating barrels that are allowed to whip). To take this logic to the extreme, if you had a truck size hunk of steel with a bore drilled through it and fired a shot. There would be no harmonics at play. Would we see a superior result due to the lack of harmonics? Or is there any benefit from the harmonic process? If not, it seems like the wrong approach to free float a barrel. Seems like you would want to lock it in and reduce movement wherever possible. Of course, weight is an issue, and most people want a lightweight barrel and perhaps this is the only reasonable approach for a shoulder fired rifle. I guess what I'm thinking/realizing is that a free floating barrel may not be a performance enhancing feature but rather a compromise. Are we only free floating because we realize "oh crap, that thin barrel is going to bend/whip when I shoot it and if it hits the stock that's going to mess up my shot"? [/QUOTE]
