Re: bipod spring vibration
I could be out to lunch with this, but think of it this way:
If the barrel is free floating, then the vibration has to travel up the stock from the point of contact with the reciever. It has to get to the bipod springs, then work it's way back thru the stock to the reciever.
So the question is this - which is traveling faster, the initial impulse in the stock or the bullet out the barrel? Considering the vibration has to go out and back, it makes up for the barrel being longer if both were the same speed.
To me, it "seems" like the bullet would exit before the vibration gets back to the reciever. But someone with some more recent physics/math/dynamics experience could probably give you a better idea. Been a long time since I've dug thru those books....
Just out of curiousity, what kind of bipod?
