Cat, isn't it true that ball powder burns cooler than extruded or double base powder? I swear, I must have read it somewhere. /ubbthreads/images/graemlins/confused.gif

All ball powder IS double base powder.
Extruded rifle powder is single base.
Flake pistol powder is double base, and the odd exception. It starts out extruded and is sliced so thin that it makes little wafers.
Ball powders were invented by Winchester/Western and they were loaded into commercial rounds with no fanfare... in fact, no one knew.
Ball powders first came on the market through Hodgdon, who sold surplus ball powder called "Ball C".
At first, they were not trusted by handloaders, because they were "different".
The "burns cooler" was what they said when ball powder first came out - kinda like a "sales point"... but it now appears that just the opposite is true. Current thinking is that extruded powder burns cooler, because it has no nitroglycerin.
It's sort of a moot point, because no one has ever been able to demonstrate that either powder has shorter barrel life than the other.
