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.

It is only simple physics if you are talking about a perfect gas and you are not talking about complex chemical reactions. In this case, this is not a perfect gas and it is a chemical reaction. There is a solid -powder- and a gas -oxygen. The chemical reaction started by athe primer causes the solid to become a gas. The gases created depend on the chemical make up of the solid. The amount of gas is dependent on the chemical make up of ingredients. In this case the change in ingredients is the powder, while oxygen is fairly constant. There are other variables, but unless I quickly move a couple thousand feet in elevation or a severe weather front comes through in the minute or two between shots, these other variable will not have an effect from shot to shot.

I prefer classic.
