Unclenick,

Totally following you. I have enough credits to almost qualify for a minor in "music theory" and while my electronics background is sorely lacking I still have to be able to calculate free space loss between antennas for my current job.

I looked up the modulus of elasticity for steel (in various alloys and hardness) but couldn't find a way to translate that data into a form useable to answer the question, "how quickly will barrel steel lose energy?"

Intuitively the answer is, "longer than it takes to get the bullet out the bore." But my experience with mild steel in a machine shop is that it is a very poor conductor of compression, so I am interested in how much muzzle deformation actually occurs by the the time the bullet exits.
