[QUOTE="Buffalobob, post: 97665, member: 8"] The graph looks much better. (obviously I am an old school engineer who likes and reads graphs). The lack of any difference between temperatures on the first shot is more apparent. As you mention the missing piece of data is the pre-shoot temperature. This would give you a better estimate of net increase between shots. It was my understanding that smaller case capacities would generate higher pressure but the confounding factor of the slightly slower burn rate of RL22 vs 4350 "confounds" the analysis. I will take a gander around the house for a thermocouple. I can't think of anything that my son has torn apart recently that had one. [/QUOTE]
