[QUOTE="hemiford, post: 1142536, member: 72104"] Well thank you Gentlemen. Very interesting so far. It seems to me that there might be several angles of attack to this goal of controlling barrel vibrations and, ultimately, making the rifle's shots more identical. Here's an analogy: I have built home stereo speakers and can tell you that, if possible, you want a HEAVY cabinet that is accoustically DEAD. No cabinet vibrations. Now, if you can somehow dampen the rifle barrel in a similar way so it doesn't vibrate, you will increase its accuracy. Maybe the carbon fiber wrap does this. A thicker/heavier barrel will do this. Maybe wrapping the barrel in thick tar paper will do this. Maybe three pounds of silly putty. Anything to dampen vibrations. OK, another angle of attack might be the barrel mounting, already somewhat discussed here. I guess I can generalize by saying that any mounting method which minimizes barrel vibrations is a good mounting method. This is sort of where I started the thread. If a barrel weighs 8~~10 pounds (which by the way is part of my evil secret plan) and the action weighs 2.5 pounds, I cannot see grabbing the action and hanging the barrel off the end of the action. I CAN see grabbing the barrel and hanging the action off the end of the barrel. The stock cannot be flexible, at all, in any case. Working downstream, I guess I could then continue to argue that your shoulder would be the next problem area, but at this point, I quit the theoretical rambling. Anyway, I started the thread to be about barrel mounting. I realize my plan is not typical, but this barrel I'm considering will be 1.350 OD for ten inches, then tapering to about 1.100 at 38 inches total. Mounted on a Rem 700 clone. If I bed the full 10-in 1.350 section, I cannot believe there is any piece of wood that would bend/distort a 1.350 piece of steel, no matter how damp the wood gets, or what a temperature change might do to the wood. So, there is my current interest, but still I'm all ears about vibration control in general, even though you might think it off-topic. [/QUOTE]
