Your bipod springs are touching your barrel?

Re: bipod spring vibration

bipod is properly loaded, doesnt hop when fired. but the springs on it ring like a tuning fork. so much so that it sounds very loud while in cheek weld. if its transmitted through my cheek bone easily, then it is transmitted through the barrel too. after watching the lesson on trigger control with the whole tuning fork idea, it kinda got me thinkin.

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?
 
Re: bipod spring vibration

its a harris swivel i put some shrink tubing over the springs to dampen any vibrations and to shut it up. i just got to thinking about it after watching the trigger school lesson
