Recently I tried to find any infirmation about powders, their specifics, how to use etc. I've found the article with piece of info about it. They say you should load apr. 90% of the case volume with powder because it needs room to flame properly. Then they talk about flattetened ball powder. By their opinion it is mostly used in shotguns to prevent powder movement to the wad so the wad is squeezing the powder load. Can anyone explain the reasons of this? Why there is no room in shotgun cartridges and why it is so bad if powder moves toward the wad in it?
Any advices about proper literature or articles are apreciated |

Use this data to help understand the relationship between gunpowder burn speed, bullet weight, and case capacity. In general, you'll notice that faster gunpowders will be used with the light bullets used in a particular cartridge, but that is a guideline, not universal -
Hodgon Load Data Hodgon Reloading Education This page contains links that describes the application of the gunpowders sold by Hodgon: https://www.hodgdon.com/products/smokeless-powder/ This page contains links that describe the applications for Alliant gunpowders: http://www.alliantpowder.com/products/ Alliant load data: http://www.alliantpowder.com/reloaders/index.aspx Accurate gunpowders: http://www.accuratepowder.com/products/rifle/ http://www.accuratepowder.com/load-data/ Vihtavuori Reloading Powders: http://www.vihtavuori.com/en/powders/overview.html http://www.vihtavuori.com/en/reloading-data/about-reloading.html Western gunpowders; this page includes links to Accurate, Ramshot, and Norma gunpowders: https://www.westernpowders.com/index.php?route=common/home That pretty well covers the products available in the US (over 100 gunpowders are available here). Use published load data; advice to use gunpowders that fill the case to 90% or more is good advice in general. |

Any advices about proper literature or articles are apreciated First time I tried to make a shotgun blank, i loaded the regular 27gr of WST, but left out the 1 1/8 oz of shot. Instead of a spectacular bang, there was a pop and bunch of half burnt powder flying out of barrel behind the wad. |
