Ken, I agree with your assement of my post to you. How ever you point out the difficulty in setting up expirments. There is also the difficulty in utilizing the data you have developed. One tool in this process is developing a baseline or control inorder to have a comparison of factors for future observation. Comparing the effect of 50,000 psi to 60,000 would show the relative difference and by using your comparitive ratio one could have a basic idea of what effects of the number of shots fired at a given pressure will have on ones barrel. Perhaps this is of greater value to the average shooter than a long and drawn out process that may in fact just varify what you have developed through mathmatics.
