[QUOTE="Slim_T, post: 257729, member: 15132"] I believe the thought was that a chart or relative performance index (RPI) or powder temperature sensitivety would be a useful tool. Certainly, each instance of a bullet-rifle-load combination is going to produce different results, but a RPI allows you to gain an idea of performance and can assist in selecting a power before you spend much time investigating it. Similar to the use of a burn rate chart. RPI charts are quite common in the aircraft and auto industies. Having said all that, as you mentioned, I intend to characterize the temperature versus velocity of my 300 wsm load (using reloader 19) so that I can better hit the target and game. I'll post the data as I gather it. [/QUOTE]
