Introduction to Group, Batch and Cartridge screens
The main Reloading Studio cartridge assembly screen is the most complex screen in the application. It is also the most exciting. This is where you get to assemble your ammo, record performance and plan load experiments.
While there are detailed knowledge-base articles covering fields and options related to load development screens, this document will cover some of the overarching concepts for major components:
- Cartridge Screen.
- Cartridge Development group.
- Batch (i.e. cartridge batch screen, not 'batch' field).
The ‘Cartridge’ screen is a term used throughout the Reloading Studio manual to refer to the main application screen where you assemble ammunition.
A batch is the primary data section/record where components are selected and grouped together to create a cartridge.
A batch is a specific record describing/documenting a single unique cartridge. If you are testing various charge weights, a batch is a cartridge where only one powder weight is selected. For example, if you are loading 5 rounds for a ladder test, then you will create 5 batches (don’t worry, batches can be copied and edited, to save on data entry time). There may be many batches, grouped together for an experiment.
Similarly, if you are testing charge volume for some specific ammunition, then seating depth, then brass (length, full length sized, fire formed), weighted brass, selectively measured bullets and other tweaks, then each individual cartridge specification is referred to as a batch.
It is possible to group various batches in some sort of relationship (e.g. development for a completion or hunting), the actual relationship is something up to the user to decide. For example, grouping batches to develop a hunting or competition load. This group of batches is called a Cartridge Development Group.
Cartridge Development Group
The Cartridge Development Group screen is a term used to describe a collection of batches.
For example, you maybe developing a cartridge using Trail Boss powder and certain type of projectile. You may be tweaking the seating depth, case length, charge weight, etc. Each one of these experiments will be recorded in its own record (batch). However, all of these records are related to the same cartridge development activity and often to a specific firearm. To organise these records logically in the application, we collate these batches into a single Cartridge Development Group.
