<wengv>single-based vs double-based? ball vs. stick
I am new to reloading. I am wondering what are the basic characteristics between single-based powder and double-based powder (also ball powder and stick powder). I know they have different components. My question is what differeneces are in their chemical properties.

<Loren>Stick vs Ball is merely a shape difference. Ball powders meter better and usually load more densely, but some are dangerous for reduced loads (winchester 760 etc. in particular). The stick powders are often used to get 95+% of the case filled with powder for most uniform burning.
Single base powders are nitrocellulose( I think Cotton is the preferred cellulose source) while double base poweders are up to 20% nitroglycerine as well as nitrocellulose . Both powders have coatings added to control burn rate and improve handling.
Most of the powder manufacturers have nice web sites that detail their powders and how they are made and used. Most reloading stores have free brocures too.

aHunterFrom what I have heard, ball powders are somewhat temperature sensitive. So for tropical hunting stick to stick powders.
I�ve had very good results with IMR and H 4350 in �06. 4198 to 4831 covers a lot of cartridges.
I�m very fond of Vihtavuori for handgun reloading, although for first time reloading a cartridge or unusual calibers what would I do without Unique?
Good shooting! H

1894The speer book and perhaps the site has an excellent section on powders.

AtkinsonIt depends on what you are shooting them in and for what the cartridge was designed for...Check your reloading books for the specific caliber that your using and see which gives the best velocity, then try it for accuracy...
They all have a place in the whole scheme of things, I wouldn't concern myself with the theory and whys an wherefores....
