[QUOTE="Bob Wright, post: 2867823, member: 104363"] That extra heat in RE17 is certainly showing up at .5° F more per trigger pull in this experiment. Doesn't sound like much. But the inside surfaces see 3990°F for a few less milliseconds (bullet speed is faster). There is more heat going on with RE17 at the interior surface that only shows 5° more on the outside. If I go with Hodgdon powders versus Reloder powders in the same manual for one cartridge, Hodgdon runs slower in all my chamberings and will pressure out quicker in speed tests versus Reloder. Not that it's bad but it's significant in speed. [/QUOTE]
