If there’s been a study on the flame temperature of smokeless powder, is there a chart showing the differences?
In particular, in shooting say “lever action silhouette” or some other “game” where there are multiple rounds shot, burning temperature may affect the POI of the last few rounds.
When I test ammo, I’ll often let the barrel cool. But in the field or at a competitive game I will shoot as fast as needed.
Finally, double base powders, do they burn hotter?
Temperature in a compressed gas corresponds to pressure. That is simple physics.
The Hodgdons powder manuals list pressure with most of their load data. The loads listed with lower pressure will have lower temperature. What is not listed in the manual is peak pressure duration. The duration of peak temperature is just as conducive (or more so) to barrel heating (and flame erosion) as is peak temperature.
