Re: Ball verses Extruded powder
[ QUOTE ]
Ball powders are more sensitive to temperature, so velocities will vary much more with ball powders, from summer to winter.
Also, ball powders burn dirtier than extruded powders.

It is very true that the temp sensitivity is greater with ball vs extruded. Most of the older ball powders are "dirtier" but some of the new powders such as H869 are MUCH improved.
In short, ball powders can be very good for LR. It boils down to what your rifle likes.
Long range shooting is a process that ends with a result. Once you start to focus on the result (how bad your last shot was, how big the group is going to be, what your buck will score, what your match score is, what place you are in...) then you loose the capacity to focus on the process.

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

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.
