If I could obtain access to the means to accurately measure the barrel's expansion and contraction this gun might be sacrificed to research. See above, Chuck's proposal will get the information you/I/we want. Strain gauges are based on the change of electrical resistance with the "stretch" of the barrel.

Respectfully,
